Mercury is the innermost and smallest planet in the Solar System, orbiting the Sun once every 87.969 Earth days. The orbit of Mercury has the highest eccentricity of all the planets, and it has the smallest axial tilt. It completes three rotations about its axis for every two orbits. Mercury is bright when viewed from Earth, ranging from −2.3 to 5.7 in apparent magnitude, but is not easily seen as its greatest angular separation from the Sun is only 28.3°. Since Mercury is normally lost in the glare of the Sun, unless there is a solar eclipse it can be viewed from Earth’s Northern Hemisphere only in morning or evening twilight, while its extreme elongations occur in declinations south of the celestial equator, such that it can be seen at favorable apparitions from moderate latitudes in the Southern Hemisphere in a fully dark sky. — Wikipedia

- Researchers say space atomic clocks could help...on December 5, 2022 at 5:15 pm
Studying an atomic clock on-board a spacecraft inside the orbit of Mercury and very near to the Sun could be the trick to uncovering the nature of dark matter.
- Mercury has magnetic stormson March 31, 2022 at 2:16 pm
An international team of scientists has proved that Mercury, our solar system's smallest planet, has geomagnetic storms similar to those on Earth. Their finding, a first, answers the question of whether other planets, including those outside our solar system, can have geomagnetic storms regardless of the size of their magnetosphere or whether they have an Earth-like ionosphere.
- Why does Mercury have such a big iron core?on July 2, 2021 at 7:43 pm
A new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle. For decades, scientists argued that hit-and-run collisions blew away much of Mercury's rocky mantle and left the big, dense, metal core inside. But new research reveals that collisions are not to blame -- instead, the density, mass and iron content of a rocky planet's core is influenced by its […]

Geoscientists have found the largest extraterrestrial diamonds ever discovered - a few tenths of a millimeter in size nevertheless - inside meteorites. Together with an international team of researchers, they have now been able to prove that these diamonds formed in the early period of our solar system when minor planets collided together or with large asteroids. These new data disprove the […]

Despite Mercury's 400-degree Celsius daytime heat, there is ice at its caps. And now a study shows how that Vulcan scorch probably helps the planet closest to the sun make some of that ice.
