Planet Rock

fourth planet from the sun in our Solar System. Mars got its name from the Roman God of War. Mars means Ares in Roman. Ares is the Roman god of war. Mars is actually much smaller than Earth. It is the 7th biggest planet in our Solar System. The mass of Mars is 6.4169 *1023. That is slightly more than 10% of the Earths mass. It’s radius is 2,106 miles (3,390 Km). The force of gravity at the surface of Mars is 3,711 meters per second. Mars is a terrestrial planet which means that the planet is…

and Money Visiting Mars There is so much data out there in this world that leads humans to want to go to other planets. Not only want to, but eventually people may need to go to other planets and there is a chance that it could become a huge part of life and a huge step up from where humans are today. A new galaxy has been discovered called TRAPPIST-1 which has seven Earth like planets, three of them suitable for life. If humans could get to this galaxy which is only 39 light years away, it…

The inner solar system planets Mercury, Venus, Earth, and Mars are fascinating because they orbit closest to the sun. In fact, a human could possibly stand on the four inner planets, unlike the four outer planets that are made of gas. Earth, Mercury, Venus, and Mars provide crucial information for researchers who need additional information about the four inner planets. I chose this topic because I thought it would be facilitating to learn about a different world, and how they are similar, yet…

Space has a vast history filled with fact and fiction. The thought of beings beside humanity seems like foolishness to some, but to others it is almost a certainty. The with massive void of space humanity lives in is filled thousands of stars, planets, and rocks extraterrestrial life seems more than possible. Now, with modern science advancements it…

The eighth planet, Neptune, is surprisingly dynamic. With many thinking Uranus could be its twin, the real facts of Neptune are lost. Neptune has unique amount of moons, rings, temperature, gases, and also unique name. Neptune was discovered in the 1800s due to astronomers observing Uranus. Uranus’s placement wasn't exactly where they thought it was. They determined that there was another planet’s gravity pulling on Uranus. On September 23, 1846, the newly discovered planet was named after the…

everyday lives such as rotation. For example, Every approximately 23 hours 56 minutes and 4.1 seconds Earth makes a full rotation on our planet on its axis, Earths axis is a line we say goes through the middle of the north and south pole. During the day, half of Earth will see daylight and the other side will receive darkness, this is because one side of the planet is facing the sun receiving all the energetic heat and the other side is cooling down from the previous day. Although the side…

contrasts between Jovian and Terrestrial Planets. Firstly, Jovian Planets are visibly bigger than the Terrestrial Planets, which, are notably smaller. The reason, a Jovian Planet is bigger than a terrestrial planet due to its closeness to the sun as well as its chemical composition. Secondly, A Jovian Planet has rings while a Terrestrial Planet has none. A Jovian Planet’s rings have a composition of rock and ice that orbit the sun. However, A Terrestrial Planet does not have any composition…

Aaminah Azhar Astrobiology Spring 2015 Test 1 1. Name and describe five important steps in the formation of planets based on our current scientific understanding. a) Star and planet formation starts inside a collapsing cloud of gas and dust inside a bigger cloud called a nebula. Because of gravity pulling materials in the collapsing cloud closer together, the center of the cloud gets increasingly more compressed and because of this get hotter. The dense hot core of this collapsing cloud becomes…

that the Earth was the center of our Universe opposed to the Sun — referred to as a geocentric universe. The ancient Greeks has considered the Moon and the Sun as planets in addition to Mercury, Venus, Mars, Jupiter, and Saturn. The days of the week were later named after the gods who were believed to have been represented by these “planets”. In the third century B.C.E., Aristarchus of Samos presented the first known model in which the Sun was at the centre of the universe and the Earth…
