  • Planet Positions: 1 Planet Positions
    Planet Positions: 1 Planet Positions As the planets orbit the Sun, they move around the celestial sphere, staying close to the plane of the ecliptic. As seen from the Earth, the angle between the Sun and a planet -- called the elongation -- constantly changes. We can identify a few special configurations of the planets -- those positions where the elongation is particularly noteworthy. The inferior planets -- those which orbit closer INFERIOR PLANETS to the Sun than Earth does -- have configurations as shown: SC At both superior conjunction (SC) and inferior conjunction (IC), the planet is in line with the Earth and Sun and has an elongation of 0°. At greatest elongation, the planet reaches its IC maximum separation from the Sun, a value GEE GWE dependent on the size of the planet's orbit. At greatest eastern elongation (GEE), the planet lies east of the Sun and trails it across the sky, while at greatest western elongation (GWE), the planet lies west of the Sun, leading it across the sky. Best viewing for inferior planets is generally at greatest elongation, when the planet is as far from SUPERIOR PLANETS the Sun as it can get and thus in the darkest sky possible. C The superior planets -- those orbiting outside of Earth's orbit -- have configurations as shown: A planet at conjunction (C) is lined up with the Sun and has an elongation of 0°, while a planet at opposition (O) lies in the opposite direction from the Sun, at an elongation of 180°. EQ WQ Planets at quadrature have elongations of 90°.

Phobos, Deimos: Formation and Evolution Alex Soumbatov-Gur The moons are confirmed to be ejected parts of Mars’ crust. After explosive throwing out as cone-like rocks they plastically evolved with density decays and materials transformations. Their expansion evolutions were accompanied by global ruptures and small scale rock ejections with concurrent crater formations. The scenario reconciles orbital and physical parameters of the moons. It coherently explains dozens of their properties including spectra, appearances, size differences, crater locations, fracture symmetries, orbits, evolution trends, geologic activity, Phobos’ grooves, mechanism of their origin, etc. The ejective approach is also discussed in the context of observational data on near-Earth asteroids, main belt asteroids Steins, Vesta, and Mars. The approach incorporates known fission mechanism of formation of miniature asteroids, logically accounts for its outliers, and naturally explains formations of small celestial bodies of various sizes.

Not one star in the image can be seen by the naked eye. 4. Color of star reflects its surface temperature. Eagle Nebula. M 16 1. Messier 16 is a conspicuous region of active star formation, appearing in the constellation Serpens Cauda. This giant cloud of interstellar gas and dust is commonly known as the Eagle Nebula, and has already created a cluster of young stars. The nebula is also referred to the Star Queen Nebula and as IC 4703; the cluster is NGC 6611. With an overall visual magnitude of 6.4, and an apparent diameter of 7', the Eagle Nebula's star cluster is best seen with low power telescopes. The brightest star in the cluster has an apparent magnitude of +8.24, easily visible with good binoculars. A 4" scope reveals about 20 stars in an uneven background of fainter stars and nebulosity; three nebulous concentrations can be glimpsed under good conditions. Under very good conditions, suggestions of dark obscuring matter can be seen to the north of the cluster. In an 8" telescope at low power, M 16 is an impressive object. The nebula extends much farther out, to a diameter of over 30'. It is filled with dark regions and globules, including a peculiar dark column and a luminous rim around the cluster.

  • 5 the Orbit of Mercury
    Name: Date: 5 The Orbit of Mercury Of the five planets known since ancient times (Mercury, Venus, Mars, Jupiter, and Saturn), Mercury is the most difficult to see. In fact, of the 6 billion people on the planet Earth it is likely that fewer than 1,000,000 (0.0002%) have knowingly seen the planet Mercury. The reason for this is that Mercury orbits very close to the Sun, about one third of the Earth’s average distance. Therefore it is always located very near the Sun, and can only be seen for short intervals soon after sunset, or just before sunrise. It is a testament to how carefully the ancient peoples watched the sky that Mercury was known at least as far back as 3,000 BC. In Roman mythology Mercury was a son of Jupiter, and was the god of trade and commerce. He was also the messenger of the gods, being “fleet of foot”, and commonly depicted as having winged sandals. Why this god was associated with the planet Mercury is obvious: Mercury moves very quickly in its orbit around the Sun, and is only visible for a very short time during each orbit. In fact, Mercury has the shortest orbital period (“year”) of any of the planets. You will determine Mercury’s orbital period in this lab. [Note: it is very helpful for this lab exercise to review Lab #1, section 1.5.] Goals: to learn about planetary orbits • Materials: a protractor, a straight edge, a pencil and calculator • Mercury and Venus are called “inferior” planets because their orbits are interior to that of the Earth.

  • Field Astronomy Circumpolar Star at Elongation ➢ at Elongation a Circumpolar Star Is at the Farthest Position from the Pole Either in the East Or West
    Field Astronomy Circumpolar Star at Elongation ➢ At elongation a circumpolar star is at the farthest position from the pole either in the east or west. ➢ When the star is at elongation (East or West), which is perpendicular to the N-S line. ➢ Thus the ZMP is 90° as shown in the figure below. Distances between two points on the Earth’s surface ➢ Direct distance From the fig. above, in the spherical triangle APB P = Difference between longitudes of A and B BP = a = co-latitude of B = 90 – latitude of B AP = b = co-latitude of A = 90 – latitude of A Apply the cosine rule: cosp− cos a cos b CosP = sinab sin Find the value of p = AB Then the distance AB = arc length AB = ‘p’ in radians × radius of the earth ➢ Distance between two points on a parallel of latitude Let A and B be the two points on the parallel latitude θ. Let A’ and B’ be the corresponding points on the equator having the same longitudes (ФB, ФA). Thus from the ∆ O’AB AB = O’B(ФB - ФA) From the ∆ O’BO o O’B = OB’ sin (90- θ) Since =BOO ' 90 = R cos θ where R=Radius of the Earth. AB= (ФB - ФA) R cos θ where ФB , ФA are longitudes of B and A in radians. Practice Problems 1. Find the shortest distance between two places A and B on the earth for the data given below: Latitude of A = 14° N Longitude of A = 60°30‘E Latitude of B = 12° N Longitude of A = 65° E Find also direction of B from A.

  • Introduction No. 104 July 2020
    No. 104 July 2020 Introduction I hope you are in good health as July’s Binocular Sky Newsletter reaches you. Although it is primarily targeted at binocular (and small telescope) observers in the UK, this particular community extends well south of the Equator. So welcome! Astronomical darkness, albeit short, return for locations south of about 53.5°N this month and, as binocular observers with our combination of maximum portability and minimal set-up time, we are well suited to take advantage of what this darkness reveals. I hesitate to write this, given recent history of our dashed expectations of “promising” comets, but we have another one, C/2020 F3 (NEOWISE). It’s visible in SOHO images and might just live up to expectations. (But it might not!) The binocular planets, Uranus and Neptune are becoming visible in the pre-dawn sky, as is Ceres but the short darkness means that there is only one suitable lunar occultations of a star, a dark-limb reappearance. If you would like to receive the newsletter automatically each month, please complete and submit the subscription form. You can get “between the newsletters” alerts, etc. via and . Binocular Sky Newsletter – July 2020 The Deep Sky (Hyperlinks will take you to finder charts and more information on the objects.) The all-sky chart on the next page reveals a lot about the structure of the Milky Way galaxy. Running in a strip down the middle, coinciding with the Milky Way itself, is the orange band of open clusters. Here, we are looking along the plane of the spiral arms which, of course, is where the star-forming (and, hence, open cluster forming) regions are.

  • Summer Sp Target Information
    SUMMER SP TARGET INFORMATION ALGIEBA (g LEO) BASIC INFORMATION OBJECT TYPE: Binary Star CONSTELLATION: Leo BEST VIEW: Late April DISCOVERY: Known to Ancients DISTANCE: 131 ly BINARY SEPARATION: 4” (170 AU) ORBITAL PERIOD: ~500 yr. APPARENT MAGNITUDE: 1.98 DISTANCE DETERMINATION After measuring the shift in position of the star relative to background stars as Earth orbits the Sun, simple trigonometry can yield the distance. The Hipparcos satellite was launched in 1989 to create a comprehensive catalog of trigonometric parallax measurements from space. The distance quoted above is from this catalog. NOTABLE FEATURES/FACTS • William Herschel discovered Algieba’s binary nature in 1782. • Both components of Algieba have evolved beyond the main sequence. They began their lives as B-type stars, and they will end their lives as white dwarfs. • In 2010, a team including former UT astronomer Arte Hatzes discovered a planet orbiting Algieba A. The planet is nine times the mass of Jupiter and orbits the star in 1.2 years at an average distance of 1.2 AU. SUMMER SP TARGET INFORMATION MESSIER 97 (THE OWL NEBULA) BASIC INFORMATION OBJECT TYPE: Planetary Nebula CONSTELLATION: Ursa Major BEST VIEW: Early May DISCOVERY: Pierre Mechain, 1781 DISTANCE: ~2000 ly DIAMETER: 1.8 ly APPARENT MAGNITUDE: +9.9 APPARENT DIMENSIONS: 3.3’ DISTANCE DETERMINATION The distances to most planetary nebulae are very poorly known. A variety of methods can be used, providing mixed results. In many cases, astronomers resort to statistical methods to estimate the distances to planetary nebulae. Although we don’t have accurate distances for most of the planetary nebulae in the Milky Way, we do know exactly how far away the Large Magellanic Cloud is.
