    group of planets that is being pulled together by a single, bright, yellow star called the “Sun”. This group of planets, along with the Sun itself, are called the “Solar System”. In the Solar System, there are nine planets, which are then again grouped into two groups; the terrestrial planets and the Jovian planets. The terrestrial planets are Mercury, Venus, Earth, and Mars, while the Jovian planets are Jupiter, Saturn, Uranus, and Neptune. I mentioned earlier that there are nine planets, but there

    Neptune; The Final Planet Eighth and last planet from the Sun; Neptune was discovered in a joint British-French-German effort with Johann Gottfried Galle, Urbain Le Verrier and John Couch Adams in 1846. Neptune was officially named after the Roman god of the sea due to its blue coloration not long after the original name Le Verrier; suggested by Galle, was declined by the international astronomical community. This interesting ice giant has had some major scientific theories, findings, and accomplishments

    Pluto is a planet, because it consists of all of the qualities that the other planets have. According to usatoday.com, “Harvard science historian Owen Gingerich, who chairs the IAU planet definition committee argued that a planet is a culturally defined word that changes over time, and that pluto is a planet.” In an article from missionscience.nasa.gov it states that “According for something to be considered a planet, it must consist of three things. First it must orbit the Sun, second it must be

    Pluto is not a planet because it doesn’t have all the criteria needed to be defined as a planet. According to Snowbrains.com, a planet needs to orbit the sun, have enough gravitational pull itself into a spherical shape, and clear its neighborhood by being a dominant source of gravity. The text from Discoveryeducation.com states, “In 2005, space probes identified a Kuiper Belt object named Eris that is more massive than Pluto. Eris was classified as a dwarf planet within the Kuiper Belt.” In an article

  • Mercury Planet Research Paper

    Semester Paper Earth has always been known as the only habitable planet in our solar system, until now. A recent exploration has discovered a new alien lifeform on the planet Mercury. To give a better understanding of how amazing this new discovery is, I will explain the genetic makeup of humans living on Earth and the genetic makeup of the alien living on Mercury. First, this paper will explore the living conditions of each planet. Next, I will compare five organ systems found in both humans and

  • Mars Red Planet

    Mars: the Red Planet. It has intrigued us as far back as the Babylonians, who called Mars Negral. The Egyptians were the ones to give Mars a name based on color, the “Red One.” The Romans named their god of war Mars. Over the next almost 2000 years, numerous astronomers did research and observed the planet trying to understand its atmosphere and what may be on the surface. Rover landings in 1997 and 2004 gave us the first up close look at Mars’ surface and is the basis for all the skepticism we have

    1. How are the outer planets similar to each other? The outer planets are similar to each other as they all have significant amounts of hydrogen and helium in their atmosphere. All the outer planets are believed to have a rock core. They each have their own unique ring system. While none of these planets can support life as we know it, they do support many orbiting moons. The outer planets have large masses, in comparison to the inner planets. All of the outer planets are named after Greek or Roman

  • Neptune's Biggest Planet

    the 8th and farthest planet away from the Sun. It orbits 30.1 astronomical units away from the sun. Neptune takes about 165 earth years to orbit around the sun. A day on Neptune lasts only 16 hours. Seasons on Neptune last more than 40 Earth years. Neptune has a way bigger mass than Earth. Neptune is equal to 17.147 Earths. The diameter at its equator is about 30,775 miles. It is the fourth-largest planet in diameter and the third-largest in mass. Like all the other planets, Neptune turns on its

  • Pluto Planet

    Pluto should not be a planet because of its eccentric orbit and small mass. ”The IAU decided that a planet had to be an object to orbit around the sun that was massive enough for gravity to squeeze it into a spherical shape.But, also it had to gravitationally dominant, and that meant it must have cleared its surrounding region of other similarly sized objects. But with everything else out there in the Kuiper belt this was Pluto’s downfall” stated Dr Marek Kukula: "Reclassification changes the way

    Mercury Mercury is the closest planet to the sun. It is 35,980,000 miles away from the sun. Mercury is known for its speed. It takes 88 days to do one orbit around the sun (one year). But one of the weird things about Mercury is that one day in mercury is 58 earth days 15 hours and 30 minutes! The diameter of mercury is 3,032 miles (4,480 kilometers). Mercury is covered by a thin layer of minerals called silicates in the form of tiny particles. It also has deep craters.The craters were made by comets

    has been a planet since 1930. It once was in our solar system but in 2006 they decided that it wasn’t a planet anymore because it didn’t mean all the expectations. According to Discovery Education, a chihuahua is still a dog. This evidence works for Pluto because it is a very small planet but it is still a planet. Also, Jupiter is very big but it is still a planet. One of the reasons Pluto isn’t a planet is because of its size. If Pluto isn’t a planet then Jupiter shouldn’t be a planet. This proves

    Pluto should still be a planet. The new definition of planet relies on information (mass, shape) that was not and could not be known in the 1930s. “Start calling Pluto a planet right now because that’s how science makes progress, by one person at a time being convinced of the truth and adopting it. Science is not decided by votes and you are not required to submit to nonsense.” When people explain why they think Pluto is not a planet, they say it’s just too small. In, addition to Pluto’s orbit Neptune’s

However, NASA has been doing research on Pluto since the year it was founded. Speaking of which, Pluto was founded in 1931. But in all honesty, who are we to say if Pluto is a planet? We didn’t create the universe. We don’t control the planets and everything that they do. Pluto has been placed in many categories. It has been

    Pluto should not be a planet, because it does not fit in the definition of “planet.” When Pluto was found it was considered a planet. Then an astronomer found something that he called Eris, this made other astronomers talked about what made a planet a "planet." This group decided that Pluto, and Eris were not really planets because of its size and location in space. Now, Pluto and objects like it are now called dwarf planets.

According to discoveryeducation.com, A group of IAU members agreed on the following criteria for a planet in the solar system.The object must orbit the sun. The object must have a spherical shape. This shape must be created and maintained by the object's own gravity source.The object must have “Cleared the Neighborhood” around its orbit of other objects. Pluto meets two of the these three criteria

    Pluto is not a planet because in order to be classified as a planet an object needs to orbit a sun, have sufficient gravity to be round or slightly ovaled shape, not a satellite or moon of another object and lastly has removed debris in and around it’s orbit. Pluto is classified as a dwarf planet because it has not cleared all debris and it is unusually small. It is roughly half the width of united states and because it's so far from the sun, the temperature is around 375 to 400 degrees below zero

    The Terrestrial planets encompass the four closest planets to the Sun that have rocky surfaces. They have plenty of similarities, but are in no shortage of differences as well. So how do Earth, Mars, Mercury, and Venus compare and contrast? Firstly, these are all, as mentioned before, terrestrial planets. This word derives from the Latin phrasing “Terra” which translates to Earth. They are named this because they are chemically composed the same way. For instance, where once it was thought that

Pluto has been called a planet from 1930 to 2006 why change now. Pluto should be a planet because it was a planet before so why rewrite history. One important fact is that Pluto has a moon just like all the other planets. Pluto doesn’t just stop at one moon it has five that’s pretty impressive for a dwarf planet. The
