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 different from each other.
Mercury is the closest planets to the sun because it is only 35.98 million miles from the sun, whereas the other three inner planets are much farther away. Mercury orbits the sun every 88 Earth days. A day on Mercury is longer …show more content…
Also, because Mercury does not really have an atmosphere, there would be no variation in the weather conditions for plants and animals to survive. There are also no oceans or volcanoes, so people would not have to encounter tsunamis or volcanic eruptions. Since Mercury has no oceans or rivers a person could not live on Mercury, especially with the extreme temperatures. Furthermore, Mercury has no greenhouse effect because there is no atmosphere to trap the heat from the sun. After intensive research, scientists discovered that the reason Mercury has the thinnest atmosphere is because its low surface gravity makes holding onto an atmosphere in the best of circumstances a challenge. The rocky planet is constantly bombarded by solar weather. The fast-moving winds blowing constantly bombard Mercury, crashing charged particles into the planet's surface. With all these results, scientists have been able to find a substantial amount of relevant information about Mercury. They have learned that Mercury is a terrestrial planet, and humans could stand on the planet but not survive. Also, scientists discovered that on Mercury they have extreme temperature changes that humans would not be able to survive with those conditions.
Throughout time, Mercury has only been visited by two spacecrafts. The first spacecraft was called Mariner 10. …show more content…
Mars could have once harbored life. Some conjecture that life might still exist there today. In the past, oceans may have also covered the surface of Mars, providing an environment for life to exist. Although the red planet is a cold desert today, researchers suggest that liquid water may be present underground, providing a potential refuge for any life that might still exist there. Several studies have shown that there is abundant water ice beneath the
