Planetary Assignment
Mercury:
a) Mercury is a terrestrial planet because it is an inner planet and also made up of heavy planets. It is terrestrial also because it has no natural satellite and no substantial atmosphere. b) Mercury has thin atmosphere consists of helium, hydrogen, oxygen, sodium, calcium and potassium. c) Mercury has no moons. d) Mercury’s diameter is 38% the diameter or earth. e) Mercury is .38AU from the sun. f) It takes 87.97 earth days to orbit the sun and one day on mercury is 58days and 15hours. g) The crater at mercury’s poles contains water ice. h) The BepiColombo mission is still in development and will study Mercury’s unusually powerful magnetosphere and the region of space around the planet that is dominated by its magnetic field and it will also search for more possible signs of water ice.
Venus
a) Venus is a terrestrial planet because it is rock and one of the four inner planets. b) Venus has a thick carbon dioxide atmosphere along with thick toxic atmosphere which traps the heat making it the hottest planet in the solar system. c) Venus has no moons because it is so close to the sun that it’s almost impossible for it to have moons many theories state that it might have had moons before but suns gravitational force pulled it away. d) The diameter of Venus is 12,100km that is 95% of earth’s diameter. Venus fits into earth about 1.5 times. e) Venus is .722AU’s away from the sun. f) It takes 224.7 days to orbit the sun and it takes 243 days to make one complete rotation. g) Venus rotates backwards it rotates in a clockwise direction. The average temperature of Venus is 460degrees Celsius that is 410degerees Celsius hotter than the hottest dense part of the earth. The main reason it’s hot is because of its thick toxic atmosphere. h) The future mission of Venus is Venus In-Situ Explorer (VISE) which might be launched in 2013 and would perform experiments on the surface of Venus.
Mars:
a) Mars is a terrestrial planet because it is made up of core, mantle and crust. b) Mars’s atmosphere is less than 1% of earth so it doesn’t protect from sun radiation. It is made up of 95% of CO2 3% Nitrogen and 1.6% Argon and the rest is trace amounts of Oxygen’s with small particles of dust mainly iron oxide. c) Mars has 2 small asteroid sized moons and they are formed because they were first asteroids and then started to go around Mars. d) The diameter of Mars is 6,800km which is 53% diameter of earth. e) Mars is 1.522AU’s away from the sun. f) It takes 686.671 earth days to orbit the sun and 24hours 39minutes and 35seconds to make a complete rotation. g) Mars’s surface is filled with volcanoes, there are so many volcanoes on mars and some of them are large because the planet has not yet had plate tectonic action. h) MAVEN (Mars atmospheric and Volcanic Evolution) this mission will help us understand the drastic climate change.
Jupiter:
a) Jupiter is a Jovian planet because it is a gas giant yet it has a rocky core within balls of gas. b) Its atmosphere is made up of 90% hydrogen and 10% Helium. The atmospheric layers are troposphere, stratosphere, thermosphere and exosphere. There were different colors and it is red because of Nh3, White because of NH4SH, Brown because of H2O and NH4, and blue because of CO2 and H20. c) There are 50 moons and 16 provisional moons. Eight of those moons are regular satellites with prograde orbit and the remainders are irregular satellite with prograde and retrograde orbits which are further away from the Jupiter. d) Jupiter has diameter about 10times the size of earth and is 300 times more massive than earth. e) Jupiter is 5.90AU’s away from sun. f) It takes 11.86 years for Jupiter to orbit the sun and one takes 9.97 hours to make one rotation. g) Jupiter’s moon Europa has a bright surface because of sunlight reflecting off a relatively icy
Venus is named after the Roman goddess of love and beauty. The planet probably received its name because it is the brightest of the planets known to the ancients. It is the brightest object in the sky except for the Sun and the Moon, and has been known since prehistoric times. Like Mercury, it was often thought to consist of two separate bodies: Eosphorus as the morning star and Hesperus as the evening star, but the Greek astronomers knew better than this. The core accretion model Approximately…
Venus Have you been recently married and are looking to get away? Well the planet of love is perfect for you. Did you know that this planet was named after the roman goddess of love? Well this terrestrial is a fantastic get away for you and the one you love we have everything from honeymoon sweets to couples dinning at our famous asteroid café. You will never run out of fun things to do during the day because one day on this planet is 243 days and an orbit length of 225 days which means that one…
Evolution on Rocky Planets Atmosphere can be defined as a gaseous compound layer surrounding a large body mass suspended by means of gravity and centrifugal force caused by rotation [1]. Atmospheres of planets have not always been the same, its evolution comprised of complex development across million years of geologic time affected by various changes of variables inside and outside its planet [2]. Of the interest of this essay is the atmospheric evolution of a rocky planet. Rocky planet is a terrestrial…

Sun is by far the largest object in the solar system temperature: 5800 K (surface) 15,600,000 K (core The Sun is, at present, about 70% hydrogen and 28% helium by mass everything else ("metals") amounts to less than 2%. Mercury is the closest planet to the Sun and the eighth largest. Mercury has been now been visited by two spacecraft, Mariner 10 and MESSENGER Temperature variations on Mercury are the most extreme in the solar system ranging from 90 K to 700 K. Mercury is in many ways similar…
The Size of the Solar System Overview • Become familiar with the scale of the planets vs. their distances. • Get an overview of the solar system. Introduction It is easy to flip to the index of an astronomy textbook to discover that, say, the Sun lies 150 million kilometers away from Earth. It is far more difficult (if not impossible), however, to picture this distance in the human mind. In this exercise, we will learn to access the often unpalatable distances encountered in astronomy…
What is a planet? What makes Earth a planet? Just like Earth, planets need to revolve around a star. Earth revolves around the Sun, making Earth a planet. Planets need to be big enough to make a spherical shape. Earth is a sphere, making Earth a planet. Planets also need to clear a path around the star they revolve around called an orbit. Earth orbits the sun, making Earth a planet. The planets are in a specific order while they revolve around the sun. The planet closest to the sun is Mercury. Mercury…
is always in orbit of the sun, which is always spinning too. There are six major components our little solar system, starting with the sun, the inner and outer planets, stars, asteroid belts, and gravity. The sun is the star at the center. It is the biggest object in our solar system, producing light, and the gravity to keep the planets and other objects in orbit. The sun is made up in six different portions. The Corona is the Sun’s outer most atmosphere, the Chromosphere is the inner atmosphere…
The most intriguing aspect of Venus in my opinion, is that it's sidereal days (time scale that is based on the Earth's rotation measured relative to the fixed stars) outlasts it's years. This is because it takes Venus longer to rotate on its axis, due to its retrograde (counterclockwise) rotation, than it does for it to revolve around the sun. It takes 243 Earth days for Venus to complete one full rotation on its axis, and just 224.7 Earth days to make one full revolution around the sun. The length…
solar system. The solar system is made up of the Sun and the planets, where all these planets revolve around the sun by its gravity. Also, it’s consists of moons, minor planets, asteroids, gas, comets and dust. These planets are: Mercury: Mercury is the closest planet to the Sun, and the smallest planet of the solar system. It’s a bit bigger than the earth’s moon. It can be seen by the naked eyes. As Mercury is the closest planet to the sun it has a high temperature can reach to 450 C in day time…
