What does Mercury revolve around?
Mercury is the smallest planet in the Solar System and the closest to the Sun. Its orbit around the Sun takes 87.97 Earth days, the shortest of all the Sun’s planets. As seen from the Sun, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two Mercurian years.
What other space object does Mercury look like?
The planet Mercury looks a little bit like Earth’s moon. Like our Moon, Mercury’s surface is covered with craters caused by space rock impacts.
What spacecraft is currently orbiting Mercury?
NASA’s MESSENGER spacecraft orbited Mercury for more than four years….What was MESSENGER?
|United States of America (USA)
|2,443 pounds (1,107.9 kilograms)
|Mission Design and Management
|NASA / APL
|Delta 7925H (no. D307)
Are there any satellites orbiting Mercury?
About an hour after the 8:54 p.m. EDT (0054 GMT) engine burn it was official: Messenger was in a looping, 12-hour orbit around the solar system’s innermost planet. Mercury now has an artificial satellite, for the first time ever.
How many satellites do Mercury have?
|Planet / Dwarf Planet
Are there any special things on Mercury?
Mercury is the only planet which doesn’t rotate exactly once every year – instead rotating three times for every two orbits of the Sun. This is because it is nearly tidally locked to the Sun. The orbit of Mercury was important in proving Albert Einstein’s theory of General Relativity.
Can you see Mercury without a telescope?
Yes, Mercury is one of the five planets (excluding Earth) that you can see relatively easily with the naked eye. It’s the most difficult of those five planets but it is certainly possible to see without a telescope. This means that Mercury is visible for some time after sunset or before sunrise.
Is Messenger still orbiting Mercury?
MESSENGER entered orbit around Mercury on March 18, 2011, becoming the first spacecraft to do so. It successfully completed its primary mission in 2012….MESSENGER.

Has there been any exploration on Mercury?
The exploration of Mercury has a minor role in the space interests of the world. It is the least explored inner planet. As of 2015, the Mariner 10 and MESSENGER missions have been the only missions that have made close observations of Mercury. Compared to other planets, Mercury is difficult to explore.
Does Mercury rotate on its axis?
Mercury rotates slowly. One rotation takes nearly 59 Earth days to complete. Mercury does not tilt on its axis, therefore the Sun would constantly be situated on the horizon at the poles). The image above shows how Mercury completes three rotations around the Sun for every two orbits.
Does Mercury have active volcanoes?
Active volcanoes occur on planets that are still hot. In general, the larger the planet, the slower it cools. Small planets or moons, like Mercury and our Moon, have cooled to the point that they are no longer hot enough to melt rock. Larger planets, like Earth and Venus, are still hot and still have active volcanism.
What was the name of the first spacecraft to orbit Mercury?
When it arrived in March 2011, MESSENGER (ME rcury S urface, S pace EN vironment, GE ochemistry, and R anging) became the first spacecraft to orbit Mercury. The mission came to an abrupt end on April 30, 2015, when the spacecraft, which had run out of fuel, crashed onto the planet’s surface. [ First Photos of Mercury from Orbit]
How to make the planets revolving around the Sun?
Find an open area in your classroom, school or outside with enough space for students to re-enact the planets revolving around the sun. On the floor, using masking tape or, if outside, using sidewalk chalk, draw one circle (the sun) with 8 concentric circles surrounding it.
How often does Mercury orbit around the Sun?
Mercury’s orbit Mercury speeds around the sun every 88 Earth days, traveling through space at nearly 112,000 mph (180,000 km/h), faster than any other planet. 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.
How is Mercury different from the rest of the Solar System?
From the surface of Mercury, the Sun would appear more than three times as large as it does when viewed from Earth, and the sunlight would be as much as seven times brighter. Mercury’s surface temperatures are both extremely hot and cold. Because the planet is so close to the Sun, day temperatures can reach highs of 800°F (430°C).
