Planet

The four planets that make up the terrestrial planets are commonly known to us as Mercury, Venus, Earth, and Mars (Kay, 2013, p. 216). The reason that terrestrial planets are grouped separately from the rest of the solar system is because they are all structured very similarly and all have surfaces most like that of the planet Earth. Another aspect that separates these four planets from all others is the fact that they are all located the closest to the Sun. Terrestrial planets can be easily…

Pluto is a Dwarf Planet This astronomical study will define the development of Pluto from being a planet to a “dwarf planet” in the solar system. Pluto is a planet with about 30 to 49 astronomical units away from the sun, and it takes about 5 hours for the light of sun to reach its surface. Pluto also has an orbit of 248 years, which makes the longest orbital time period for a planetary object in the solar system. The mass of Pluto is 1.303±0.003)×1022 kg and the radius of the planet is 0.1863…

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…

eight planets, their moons, asteroids, meteoroids, and comets. These eight planets in our solar system are generally categorized into two types: terrestrial planets, and gas giants. The word terrestrial comes from the Latin word terra which means earth, land, or territory according to dictionary.com. From this, terrestrial planets literally means Earth-like rocky planets. This contrasts from gas giants, since gas giants are mostly composed of gases, as assumed from its name. Terrestrial planets…

ASTROPHYSICS Methods used to search for extrasolar planets Lucky Ruangsiri 24.02.2016 Extrasolar planets are planets that revolves another star apart from our solar system. The human race has found nearly 2000 confirmed extrasolar planets by the year 2016, and this has fuelled the search for extra-terrestrial life as we scour the universe for anything out there. How do we discover these planets that are light years away from the earth? An extrasolar planet detection technique is the…

Pluto, is it a Planet? Pluto is a planet! No, Pluto is not a planet! The science community ignored what other people had to say about why Pluto should be a planet. Yet, the discoverer classified Pluto as a planet, but the IAU ripped his finding apart, and reclassified it as a dwarf planet. Pluto lost its title "planet" due to the International Astronomical Union (IAU) definition of planet, but NASA is still receiving new information from New Horizons. Pluto was a "planet" that wasn't discovered…

have such horrendous conditions, but the planet Neptune does as well! The name Neptune originates from the Roman god Neptune. Which means “The God of the Sea” in in Roman mythology, which is the equivalent of the Greek god Poseidon. Some people actually venerate these gods in a ceremony called Lectisternium, and offered food to gods and goddesses. Neptune is also the fourth biggest planet in our solar system. Its mass is about 1.0247e26 kg. The planet takes about 165 years to orbit…

Should Pluto be a dwarf planet or a planet? There has been lots of debate on whether it should be a dwarf planet or a planet. Their is not a big difference between the dwarf planets and the planets. The only difference between the two is that a dwarf planet has an orbit around it which is not cleared out and the orbit around a planet is cleared out. Pluto has been a dwarf planet since 2006. It turned into a dwarf planet because it is lacking certain details and the orbit around it was…

19. Pluto is no longer considered a planet, and is considered a dwarf planet because it has not “cleared the neighborhood around its orbit. This saying pretty much means that Pluto has gained control of the gravity around it. So astronomers made a name for these planets known as the dwarf planets, to show that it is a planet that continues to orbit the sun, but it hasn’t cleared the neighborhood. 20. When meteoroids enter Earth’s atmosphere, they disintegrate before they hit the ground. When a…

Mercury, Venus, Earth, and Mars are known as the terrestrial planets. In comparison to the outer planets, they are small in size, made of denser materials, and lack a huge numbers of moons. Even though they share these common traits, they are still very different from each other. Mercury is the closest planet to the sun, yet its surface is either extremely hot or extremely cold due to the slow rotation of the planet on it's axis and the lack of atmosphere. It is also unique in that it's core is…
