How long does it take mercury to do a full revolution around the sun?

Answer 1

A complete orbit by Mercury around the Sun takes 88 Earth days. So that is Mercury's "year."

The slow rotation of the planet (about 58.6 Earth days) is due to resonance with the Sun, giving Mercury 3 rotations for every 2 orbits. The effect of this is that a "solar day" (sunrise to sunrise) on Mercury lasts 156 Earth days!

Answer 2

It takes Mercury 88 days to revolve around the sun. Mercury has an iron core which makes up most of its weight. It takes 59 earth days to rotate once. It's the smallest planet, but also the closest to the sun. At night, it can reach temperatures of -175 degrees Celsius while in day up to 295 degrees Fahrenheit.

Answer 3

Approximately 2/3 of an orbit to rotate (orbit takes 88 Earth days). That's roughly 59 days (88 x .67) to rotate, however :

Mercury orbits the sun once every 88 earth days,

and a full rotation takes 2/3 of an orbit; so a

"Mercury year" is 88 earth days, and a "Mercury day"

is 59 earth days. Who knew?

I knew, but you've missed something out. The "day" you're talking about is the

"sidereal day". The "solar day" for Mercury is 176 Earth days, or 2 x an orbit.
