This is one of the largest impact basins in the solar system and the largest feature on Mercury. The Caloris Basin is 1300 kilometers (810 miles) in diameter.
What is Mercury’s major surface features?
Along with Venus, Earth, and Mars, Mercury is one of the rocky planets. It has a solid surface that is covered with craters like our Moon. It has a thin atmosphere, and it doesn’t have any moons. Mercury likes to keep things simple.
What is Mercury’s unique features?
Its oval-shaped orbit is highly elliptical, taking Mercury as close as 29 million miles (47 million km) and as far as 43 million miles (70 million km) from the sun. If one could stand on Mercury when it is nearest to the sun, it would appear more than three times as large as it does when viewed from Earth.
What is mercury mostly known for?
Mercury is the smallest and fastest planet in the solar system. It is also the closest planet to the sun. It is named after the Roman messenger god Mercury, the fastest Roman god. The planet Mercury was known by ancient people thousands of years ago.
What are the geographic features of Mercury?
One of the most notable features on Mercury is Caloris Basin, an impact crater about 960 miles wide that formed early in the planet’s history. Mercury has no rings, no moons, and a relatively weak magnetic field. Mercury is a scarred world covered in craters, ridges, and bright debris from numerous impacts.
What is the color of mercury?
What does Mercury look like? Here you can see that Mercury is a light grey color. This is Mercury’s northern horizon as seen by the MESSENGER spacecraft during its third flyby.
What is Mercury’s length of day?
58d 15h 30m

What is a day on Mercury called?
One day on Mercury (the time it takes for Mercury to rotate or spin once with respect to the stars) takes 59 Earth days. One day-night cycle on Mercury takes 175.97 Earth days. Mercury makes a complete orbit around the Sun (a year in Mercury time) in just 88 Earth days.
How would you survive on Mercury?
Mercury can’t support life on it because it has no oxygen, no water, no air, the temperature is extremely hot and plants can’t grow on its surface so food can’t be grown. And without this people can’t live. Scientists do not believe there has ever been life on Mercury. The atmosphere on Mercury is almost non-existant.
How many times has mercury been visited?
Of the innermost rocky planets in our Solar System, Mercury has been visited the least. Only two probes have ever traveled to the planet. The first was Mariner 10, a spacecraft meant to study both Venus and Mercury. It flew by Mercury three times in 1974 and 1975.
What planet is the hottest?
Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
Can humans go to Mercury?
No, Mercury has been visited by spacecraft from Earth, but no human has ever gone into orbit around Mercury, let alone stepped on the surface. … Mercury is airless, so they would need a spacesuit to protect themselves from the vacuum of space. However, the temperatures on Mercury are much greater.
What would happen if Mercury crashed into the sun?
“Once Mercury crosses Venus’s orbit,” Laughlin says, “Mercury is in serious trouble.” So is Earth. At that point, the simulations predict Mercury will suffer generally one of four fates: it crashes into the Sun, gets ejected from the solar system, it crashes into Venus, or — worst of all — crashes into Earth.
How do you see Mercury?
As an evening star, Mercury appears in the western sky setting about an hour after the sun. As a morning star, it appears in the eastern sky rising about an hour before the sun. There must be a clear, unobstructed horizon on these occasions. Mercury usually appears as a bright “star” with a yellowish or ochre hue.
