Does Mercury rotate?
Mercury rotates slowly. One rotation takes nearly 59 Earth days to complete. However due to an orbital-rotational resonance ratio of 3:2, a fictitious observer on Mercury would see that a solar day from noon to noon would take about 176 Earth days to complete.
What is the gravity of Mercury?
3.7 m/s²
Mercury/Gravity
Is Pluto the same size as Mercury?
Mercury is a tiny black dot as it transits the Sun in 2006. In fact, Mercury is closer in size to our Moon than to Earth. In case you’re wondering, though, Mercury is still significantly larger than the dwarf planet Pluto: Pluto’s equatorial diameter is just 2,302 km, about half Mercury’s width.

How big is the Uranus?

Which is nearest planet to Earth?
Mercury
Calculations and simulations confirm that on average, Mercury is the nearest planet to Earth—and to every other planet in the solar system.
Is Mercury always facing the sun?
Mercury rotates in a way that is unique in the Solar System. It is tidally locked with the Sun in a 3:2 spin–orbit resonance, meaning that relative to the fixed stars, it rotates on its axis exactly three times for every two revolutions it makes around the Sun….Mercury (planet)

How big is the radius of mercury in miles?
The radius of Mercury is 2439.7 kilometers or 1515.96 miles. The diameter is twice the radius. What is the radius of the mercury in scientific notation? the radius of mercury in scientific notation =2.4397*10^7m What is the radius of mercury in scientific notation? Mercury has a radius of 2439.5km. In scientific notation, this would be 2.4x103km.
How many astronomical units is mercury from the Sun?
From an average distance of 36 million miles (58 million kilometers), Mercury is 0.4 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth.
How is the density of mercury different from the Earth?
Mercury’s density can be used to infer details of its inner structure. Although Earth’s high density results appreciably from gravitational compression, particularly at the core, Mercury is much smaller and its inner regions are not as compressed.
What is the temperature on the surface of mercury?
Temperatures on the surface of Mercury are extreme, both hot and cold. During the day, temperatures on Mercury’s surface can reach 800 degrees Fahrenheit (430 degrees Celsius). Because the planet has no atmosphere to retain that heat, nighttime temperatures on the surface can drop to minus 290 degrees Fahrenheit (minus 180 degrees Celsius).
