Astro Vol.11 Issue 2 Volume 11, Issue 2 NOVEMBER, 2017 Hello Space Pioneer, We did our best once again to pick the most interesting space news for our November issue. As we said goodbye to Cassini, it is time to focus on new space missions and endeavors. We strongly encourage you to search for more space news after you are done reading this issue of Astro Newsletter. The truth is, you can never get enough space news! We currently have 21 schools participating in Future Explorers Program and 10 schools in Partner School Science Program. It goes without saying that we expect mindblowing projects and everlasting friendships to be made throughout the school year. The first 3­4 weeks of the programs were already quite fruitful.

  • Planet Nine Join the Hunt for a Possible Planet!
    Planet Nine Join the Hunt for a Possible Planet! In July 2015, the New Horizons spacecraft gave us our first close look at Pluto, the most famous dwarf planet in the outskirts of our Solar System. The flyby was big news, and the data sent back to Earth revealed a world far more complex than anyone realized. Are there more worlds out there, beyond Pluto? What might such a world be like? Planet Nine tells a tale of the search for another world hidden in the darkness. Planetary scientist-explorers continually make discoveries about conditions "out there". Planet Nine follows Mike Brown and his team at CalTech as they uncover new worlds such as the remarkably bright Eris; tumbling Haumea, an Exploring Farther egg-shaped object rotating incredibly fast; and Sedna, whose High-powered telescopes peer out at the sky each night, orbit takes it deep into the far reaches of the Solar System. searching for faint light from distant worlds. Experience a night at the Subaru Telescope in Hawaii, as Brown describes his Is there a new planet beyond even these distant objects? search for worlds so far away they take thousands of years to orbit the Sun. Orbits Tell The Tale Pluto's own unusual path is a clue to chaotic activities billions of years ago. Could other distant objects "out there" follow equally odd orbits? Throughout this fascinating show, Mike Brown talks about unusual orbits and describes nights of painstaking robotic searches for new planets. His is a story of modern planet- hunting techniques that have uncovered many new worlds out beyond Neptune.

  • The Adler Planetarium Launches New Sky Show, Planet Nine, on May 28
    Media Inquiries Contact: Christina O’Connell 312-542-2424 [email protected] The Search Is On! The Adler Planetarium Launches New Sky Show, Planet Nine, on May 28. CHICAGO – May 6, 2016 – The Adler Planetarium’s newest sky show, Planet Nine, opening May 28, explores the largest of Pluto’s neighbors in the Kuiper belt and invites visitors to join in the search for a new ninth planet. In July 2015, the New Horizons spacecraft gave us our first close look at Pluto, the most famous dwarf planet in the outskirts of our Solar System. The New Horizons flyby was big news, and the pictures it continues to send back to Earth reveal a world far more complex than anyone realized. Using nothing but their wits (and high-powered telescopes and a thorough understanding of orbital mechanics), these intrepid explorers are making new discoveries about how our Solar System formed—and what it may be hiding. “We are excited to be releasing our newest sky show, especially in light of news on a potential ninth planet lurking in our Solar System,” says Mark SubbaRao, Ph.D., astronomer and Director of the Space Visualization Laboratory at the Adler Planetarium. “After Mike Brown’s Kavli Prize Laureate lecture at the Adler last spring, we decided to collaborate on a sky show. Our new sky show will provide our visitors a glimpse into the very latest science, including the evidence as to why we think another large planet is out there.” Mike Brown was one of three recipients of the 2012 Kavli Prize in Astrophysics, which was awarded for discovering and characterizing the Kuiper Belt and its largest members -- work that led to a major advance in the understanding of the history of our planetary system.

    The Planet Nine Hypothesis Konstantin Batygin,1 Fred C. Adams,2;3 Michael E. Brown,1 and Juliette C. Becker3 1Division of Geological and Planetary Sciences California Institute of Technology, Pasadena, CA 91125, USA 2Physics Department, University of Michigan, Ann Arbor, MI 48109, USA 3Astronomy Department, University of Michigan, Ann Arbor, MI 48109, USA Abstract Over the course of the past two decades, observational surveys have unveiled the intri- cate orbital structure of the Kuiper Belt, a field of icy bodies orbiting the Sun beyond Neptune. In addition to a host of readily-predictable orbital behavior, the emerging census of trans-Neptunian objects displays dynamical phenomena that cannot be ac- counted for by interactions with the known eight-planet solar system alone. Specifi- cally, explanations for the observed physical clustering of orbits with semi-major axes in excess of ∼ 250 AU, the detachment of perihelia of select Kuiper belt objects from Neptune, as well as the dynamical origin of highly inclined/retrograde long-period or- bits remain elusive within the context of the classical view of the solar system. This newly outlined dynamical architecture of the distant solar system points to the exis- tence of a new planet with mass of m9 ∼ 5 − 10 M⊕, residing on a moderately inclined orbit (i9 ∼ 15 − 25 deg) with semi-major axis a9 ∼ 400 − 800 AU and eccentricity between e9 ∼ 0:2 − 0:5. This paper reviews the observational motivation, dynamical constraints, and prospects for detection of this proposed object known as Planet Nine. 1. Introduction Understanding the solar system’s large-scale architecture embodies one of human- ity’s oldest pursuits and ranks among the grand challenges of natural science.

  • Is There a Planet Nine in Our Solar System? There Is a Lot More to Our Solar System Than Eight Planets Going Around the Sun
    Is There a Planet Nine in Our Solar System? There is a lot more to our solar system than eight planets going around the Sun. For example, between Mars and Jupiter, there is an asteroid belt filled with small rocky objects. These objects are leftover bits that didn’t get swept up when the planets were forming. Out beyond Neptune, there’s another belt of small bits of icy debris, known as the Kuiper Belt. All those icy objects in the Kuiper Belt are simply known as Kuiper Belt Objects (KBOs), the most famous of which is the dwarf planet (and former planet number nine) Pluto. Although the planets orbit in near perfect circles around the Sun, not everything in our solar system is so well-behaved. Kuiper Belt Objects and comets tend to have very ​eccentric​ orbits, meaning their paths around the Sun are more like stretched out ovals, dipping close to the Sun and then traveling much further away. All small objects of the solar system—comets, KBOs, asteroids—change their orbits as they encounter each other and the larger things of the solar system, like the planets. Earth’s orbit changes a bit, too, as it is pulled on by the gas giants Jupiter and Saturn. Our solar system is always changing, even if it might not seem like it from Earth! Because KBOs are so far away and so small, not much sunlight is reflected off them and they appear quite dim from our point of view. Only recently, have we had telescopes powerful enough to let us track the KBO orbits—and it turns out they’re pretty strange.

  • Beyond Neptune, a Chunk of Ice Is Orbiting the Sun in the Wrong Direction 17 August 2016, by Matt Williams
    Beyond Neptune, a chunk of ice is orbiting the sun in the wrong direction 17 August 2016, by Matt Williams the Panoramic Survey Telescope and Rapid Response System 1 Survey (Pan-STARRS 1). Measuring just 200 km (124 miles) in diameter, this object's orbit is tilted 110° to the plane of the solar system and orbits the sun backwards. Ordinarily, when planetary systems form, angular momentum forces everything to spin in the same direction. Hence why, when viewed from the celestial north pole, all the objects in our solar system appear to be orbiting the sun in a counter- clockwise direction. So when objects orbit the sun in the opposite direction, an outside factor must be at play. An artist’s concept of a trans-Neptunian object(TNOs). The distant sun is reduced to a bright star at a distance of over 3 billion miles. Credit: NASA Beyond the orbit of Neptune, the farthest recognized-planet from our sun, lies the mysteries population known as the Trans-Neptunian Object (TNOs). For years, astronomers have been discovering bodies and minor planets in this region which are influenced by Neptune's gravity, and orbit our sun at an average distance of 30 Astronomical Units.

  • Mysterious "Planet Nine" May Be Causing Whole Solar System to Wobble
    Name: _______________________________________ English IV: NTI Day 2 Assignment Mysterious "Planet Nine" may be causing whole solar system to wobble By Sarah Kaplan, Washington Post 10.27.16 This artistic rendering shows the distant view from "Planet Nine" back toward the sun. The planet is thought to be gaseous, similar to Uranus and Neptune. Photo: Handout from Caltech/R. Hurt, IPAC Astronomers can't see "Planet Nine." But it makes its presence known. The massive hypothetical object, which supposedly looms at the edge of our solar system, has been invoked to explain the strange clustering of objects in the Kuiper belt and the unusual way they orbit the sun. Now Planet Nine predictors Konstantin Batygin and Mike Brown of Caltech, along with graduate student Elizabeth Bailey, offer another piece of evidence for the elusive sphere's existence: It adds "wobble" to the solar system, they say, tilting it in relation to the sun. "Because Planet Nine is so massive and has an orbit tilted compared to the other planets, the solar system has no choice but to slowly twist out of alignment," lead author Bailey said in a statement. Before we go any further, a caveat about Planet Nine: It's purely theoretical at this point. Batygin and Brown predict its existence based on unusual perturbations of the solar system that aren't otherwise easily explained. (This is the same technique scientists used to find Neptune.) But the history of astronomy is rife with speculations that never bear out: The same guy who correctly predicted the existence of Neptune also believed that a planet he called Vulcan was responsible for the wobble of Mercury.

  • Présentation Powerpoint
    The Solar system Kuiper belt (30-50 AU) KBO=Kuiper Belt Object • Can be roughly divided into the classical belt and the resonances. Resonances are orbits linked to that of Neptune (e.g. twice for every three Neptune orbits, or once for every two). • Makemake (45.79 AU average), although smaller than Pluto, is the largest known object in the classical Kuiper belt (KBO not in a confirmed resonance with Neptune). • The dwarf planet Pluto (39 AU average) is the largest known object in the Kuiper belt. When discovered in 1930, it was considered to be the ninth planet; this changed in 2006 with the adoption of a formal definition of planet (3/2 resonance with Neptune) Typical objects in KBO Comparison of the orbits of scattered disc objects (black), classical KBOs (blue), and 2:5 resonant objects (green).
