The planet Mercury rotates three times about its spin axis for every two orbits about the Sun 1,2, in a 3/2 spin–orbit resonance.This unique state has been explained by an initial rapid prograde ...

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.

Mercury is locked into a 3/2 spin-orbit resonance where it rotates three times on its axis for every two orbits around the sun1,2,3. The stability of this equilibrium state is well established4,5 ...

Mercury’s orbit made its round faster than predicted. It didn’t race ahead. The precession was 93 percent accounted for, but no one could adequately explain that last seven percent.

Orbit around the Sun: Because Mercury is so close to the Sun, it has the smallest orbit of all the planets. Mercury’s year (the time it takes to orbit the Sun one time) is 88 Earth days long.

As the closest planet to the Sun, Mercury is exposed to the star's enormous gravitational field. And it's really stressful.

A visualization of Mercury's mysterious magnetic fields. ... closest to the sun, whipping around at a blazing 105,000 mph - fast enough for it to complete an entire orbit in just 88 days. And, ...

Reaching Mercury is such a challenge because “the gravitational pull of the Sun is very strong near Mercury, which makes it difficult for spacecraft to slow down enough to enter orbit around the ...

The new moon occurs on June 25. A day later, Mercury reaches its highest point in the evening sky, and on June 27, the young ...
