What are the characteristics of comets and asteroids? Big Ideas ● The distances between these bodies are huge. ● The solar system consists of the sun and a collection of objects, including planets, their moons, and asteroids that are held in orbit around the sun by its gravitational pull on them ● What natural phenomena do the motions of objects in the solar system produce?

When a dwarf planet formed, there was enough mass and gravity for it to form a sphere. A dwarf planet has objects similar in mass orbiting nearby or crossing its orbital path. Astronomers classify Pluto, Ceres, Eris, Makemake, and Haumea (how MAY ah) as dwarf planets. Pluto was once considered to be a planet, but now it has the status of a dwarf planet. All dwarf planets are smaller than Earth’s moon. The figure below locates Ceres, Pluto, and Eris. These dwarf planets each have a rocky core surrounded by a thick layer of ice. It's primarily made up of icy objects, dwarf planets, dust, and comets. The total mass of all the material in the Kuiper Belt today is estimated to be no more than about 10 percent of the mass of Earth.

  • A Deep Search for Additional Satellites Around the Dwarf Planet
    Search for Additional Satellites around Haumea A Preprint typeset using LTEX style emulateapj v. 01/23/15 A DEEP SEARCH FOR ADDITIONAL SATELLITES AROUND THE DWARF PLANET HAUMEA Luke D. Burkhart1,2, Darin Ragozzine1,3,4, Michael E. Brown5 Search for Additional Satellites around Haumea ABSTRACT Haumea is a dwarf planet with two known satellites, an unusually high spin rate, and a large collisional family, making it one of the most interesting objects in the outer solar system. A fully self-consistent formation scenario responsible for the satellite and family formation is still elusive, but some processes predict the initial formation of many small moons, similar to the small moons recently discovered around Pluto. Deep searches for regular satellites around KBOs are difficult due to observational limitations, but Haumea is one of the few for which sufficient data exist. We analyze Hubble Space Telescope (HST) observations, focusing on a ten-consecutive-orbit sequence obtained in July 2010, to search for new very small satellites. To maximize the search depth, we implement and validate a non-linear shift-and-stack method. No additional satellites of Haumea are found, but by implanting and recovering artificial sources, we characterize our sensitivity. At distances between 10,000 km and 350,000 km from Haumea, satellites with radii as small as 10 km are ruled out, assuming∼ an albedo∼ (p 0.7) similar to Haumea. We also rule out satellites larger∼ than &40 km in most of the Hill sphere using≃ other HST data. This search method rules out objects similar in size to the small moons of Pluto.

  • CHORUS: Let's Go Meet the Dwarf Planets There Are Five in Our Solar
    Meet the Dwarf Planet Lyrics: CHORUS: Let’s go meet the dwarf planets There are five in our solar system Let’s go meet the dwarf planets Now I’ll go ahead and list them I’ll name them again in case you missed one There’s Pluto, Ceres, Eris, Makemake and Haumea They haven’t broken free from all the space debris There’s Pluto, Ceres, Eris, Makemake and Haumea They’re smaller than Earth’s moon and they like to roam free I’m the famous Pluto – as many of you know My orbit’s on a different path in the shape of an oval I used to be planet number 9, But I break the rules; I’m one of a kind I take my time orbiting the sun It’s a long, long trip, but I’m having fun! Five moons keep me company On our epic journey Charon’s the biggest, and then there’s Nix Kerberos, Hydra and the last one’s Styx 248 years we travel out Beyond the other planet’s regular rout We hang out in the Kuiper Belt Where the ice debris will never melt CHORUS My name is Ceres, and I’m closest to the sun They found me in the Asteroid Belt in 1801 I’m the only known dwarf planet between Jupiter and Mars They thought I was an asteroid, but I’m too round and large! I’m Eris the biggest dwarf planet, and the slowest one… It takes me 557 years to travel around the sun I have one moon, Dysnomia, to orbit along with me We go way out past the Kuiper Belt, there’s so much more to see! CHORUS My name is Makemake, and everyone thought I was alone But my tiny moon, MK2, has been with me all along It takes 310 years for us to orbit ‘round the sun But out here in the Kuiper Belt… our adventures just begun Hello my name’s Haumea, I’m not round shaped like my friends I rotate fast, every 4 hours, which stretched out both my ends! Namaka and Hi’iaka are my moons, I have just 2 And we live way out past Neptune in the Kuiper Belt it’s true! CHORUS Now you’ve met the dwarf planets, there are 5 of them it’s true But the Solar System is a great big place, with more exploring left to do Keep watching the skies above us with a telescope you look through Because the next person to discover one… could be me or you… .

  • 1 on the Origin of the Pluto System Robin M. Canup Southwest Research Institute Kaitlin M. Kratter University of Arizona Marc Ne
    On the Origin of the Pluto System Robin M. Canup Southwest Research Institute Kaitlin M. Kratter University of Arizona Marc Neveu NASA Goddard Space Flight Center / University of Maryland The goal of this chapter is to review hypotheses for the origin of the Pluto system in light of observational constraints that have been considerably refined over the 85-year interval between the discovery of Pluto and its exploration by spacecraft. We focus on the giant impact hypothesis currently understood as the likeliest origin for the Pluto-Charon binary, and devote particular attention to new models of planet formation and migration in the outer Solar System. We discuss the origins conundrum posed by the system’s four small moons. We also elaborate on implications of these scenarios for the dynamical environment of the early transneptunian disk, the likelihood of finding a Pluto collisional family, and the origin of other binary systems in the Kuiper belt. Finally, we highlight outstanding open issues regarding the origin of the Pluto system and suggest areas of future progress. 1. INTRODUCTION For six decades following its discovery, Pluto was the only known Sun-orbiting world in the dynamical vicinity of Neptune. An early origin concept postulated that Neptune originally had two large moons – Pluto and Neptune’s current moon, Triton – and that a dynamical event had both reversed the sense of Triton’s orbit relative to Neptune’s rotation and ejected Pluto onto its current heliocentric orbit (Lyttleton, 1936). This scenario remained in contention following the discovery of Charon, as it was then established that Pluto’s mass was similar to that of a large giant planet moon (Christy and Harrington, 1978).
