Mercury's orbit. Mercury speeds ... 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.

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

Mercury, the smallest planet in our solar system and the one closest to the Sun, has long baffled scientists with its twisted ...

The orbital period of Mercury and its period of rotation are known to be in a 3/2 ratio, but the chances of the planet reaching this state seemed so small as to be unfeasible — until now.

NASA’s MESSENGER spacecraft has become the first probe ever to enter orbit around Mercury. Having settled the craft into a path around the sun’s nearest neighbor on March 17, mission ...

Mercury, like Earth, has an elliptical orbit around the sun. But since it's between Earth and the sun — and moves faster — it appears from our vantage point to change direction as it laps Earth.

RESEARCHES on ionisation and resonance potentials of mercury vapour and on its ultra-violet absorption in a non-luminous state, together with considerations from the serial type of the mercury ...

Sequence of 89 images taken by the monitoring cameras on board the European-Japanese BepiColombo mission to Mercury, as the spacecraft made a close approach of Venus on August 10th, 2021.

To date, only NASA's MESSENGER mission has entered orbit around Mercury, exploring the world from 2011 to 2015. Late next year, the joint JAXA/ESA BepiColombo mission will enter orbit around ...
