The not-planets

Posted 2015/07/14 | 3 comments

The solar system contains dozens of objects that are large enough for self-gravity to make them round, and yet are not considered planets. They include the major moons of the planets, one asteroid, and many worlds in the Kuiper belt. The ones that we have visited with spacecraft are shown here to scale with each other. A couple of items on here are not quite round, illustrating the transition to smaller, lumpier objects.

Cassini viewed Enceladus from a phase angle of 160 degrees (with the Sun nearly in front of the moon) to catch this glorious view of the moon's night side silhouetted against the E ring as it replenishes the E ring with its geysers. At upper right is the outer edge of Saturn's rings: the A ring and severely overexposed F ring.

A montage of 17 of the 18 asteroids and comets that have been photographed up close as of August 2014, when Rosetta arrived at comet Churyumov-Gerasimenko. This version is in color and shows the bodies at their correct relative (though not absolute) albedo or brightness. Not included are Vesta or Ceres, both of which are many times larger than Lutetia.
