Atmosphere of Mercury

Mercury has very little atmosphere. The planet's small size means that its gravity is too weak to hold down a normal atmosphere. There is a very thin atmosphere around the planet. Mercury's thin atmosphere...more

Eccentricity of an Orbit

Most objects in orbits move along an elliptical path. An ellipse is a shape that can be thought of as a "stretched out" circle or an oval. An ellipse can be very long and thin, or it can be quite...more

Mercury's Poles

If Uranus is the "tilted planet", Mercury might be called the "upright planet". The spin axis of Uranus, which defines the locations of the planet's North and South Poles, is tilted by 98. The spin axis...more

The Magnetic Poles of Mercury

Mercury has a weak magnetic field. Like Earth's magnetic field, Mercury's dipole field is tilted with respect to the planet's spin axis. This means that Mercury's magnetic poles and its geographic poles...more

Magnetosphere of Mercury

Mercury is the only terrestrial planet other than the Earth that has a significant magnetic field (220 nT). This field, along with the planet's high density and small size relative to the Earth, indicates...more
