What is Mercury’s distance from the Sun in km?
Mercury is the closest planet to the Sun. Its orbit around the Sun is very elliptical, like a stretched out circle, compared to those of the other planets. Mercury's distance from the Sun ranges from 28.6 million miles (46 million km) to 43.4 million miles (69.8 million km).
What is the closest distance Mercury is to the Sun?
29 million miles When it is closest to the sun, it is only 29 million miles (47 million km), but at its farthest, the distance to Mercury is 43 million miles (70 million km).
How far is Mercury from Earth in kilometers?
77 million km Mercury is an average distance of 48 million miles (77 million km) from Earth.
How long is Mercury in km?
Mercury's diameter is 3,030 miles (4,878 km), comparable to the size of the continental United States. This makes it about two-fifths the size of Earth. It is smaller than Jupiter's moon Ganymede and Saturn's moon Titan. But it's not going to stay that size; the tiny planet is shrinking.
Can we land on Mercury?
Could humans land on Mercury's surface? In spite of being so close to the Sun, and wild swings in extreme temperatures, humans could technically walk on the planet's surface. Mercury's slow rotation means it takes 59 Earth days for it to turn around once.

Mercury is named after the messenger for their gods. The Roman Mercury had wings on his helmet and shoes. He could travel very quickly from place to place. The planet Mercury moves quickly around the sun.
What is the hottest planet?
Venus It has a strong greenhouse effect, similar to the one we experience on Earth. Because of this, Venus is the hottest planet in the solar system.
Why does Mercury not fall into the Sun?
Mercury has a high-speed tangential velocity when in association with the sun. Mercury also is far enough from the sun where the gravitational pull of the sun doesn't drag Mercury in. Therefore, Mercury is speeding fast enough, along with far enough to where it doesn't just fall in.
How big is the Sun from Mercury?
Since Mercury is the closest planet to the Sun, the Sun would look much larger from Mercury than it would from any other planet in the Solar System. From Mercury, the Sun would appear to be about 2 1/2 times larger than it appears from Earth.
Does diamonds rain on Jupiter?
But in the dense atmospheres of planets like Jupiter and Saturn, whose massive size generates enormous amounts of gravity, crazy amounts of pressure and heat can squeeze carbon in mid-air — and make it rain diamonds.
Why can’t astronauts go to Venus?
Venus is not easy to visit. Its carbon-dioxide-rich atmosphere is 90 times as dense as ours, and surface temperatures average 800 degrees Fahrenheit. Its surface pressure is intense enough to crush some submarines. But that hasn't stopped human space programs from trying.
What happens if Mercury touches gold?
Freddie Mercury may have had the golden voice, but real mercury, that endlessly entertaining and dangerous liquid metal, has the golden touch. That is, if it touches gold it will immediately break the lattice bonds of the precious metal and form an alloy in a process known as amalgamation.

What planet has acid rain?
planet Venus The most acidic rain in the Solar System is found on the planet Venus, where the working fluid in the cycle of evaporation, condensation and precipitation is a sulphuric acid solution (rather than water, as on Earth).
What rains in Mars?
Because of Mars' very low atmospheric pressure, any water that tried to exist on the surface would quickly boil away. atmosphere as well as around mountain peaks. No precipitation falls however.
What planet is human landed on?

What planets can humans live on?
Kepler-62e and Kepler-62f are thought capable of hosting life. The planet Kepler-69c is located about 2,700 light-years from Earth in the constellation Cygnus. This is an illustration of the planet, which is the smallest yet found to orbit in the habitable zone of a sun-like star.
