An artist's concept of the Oort cloud. Note that the distance scale is logarithmic. Compared to the size of planetary orbits, the Oort cloud is very far away. If the Sun passed within 2 light years of another sun-like star, the stars' Oort clouds would overlap and their comets would intermingle.

Kupalo Crater is one of the youngest craters on Ceres. The crater has bright material exposed on its rim and walls, which could be salts. Its flat floor likely formed from impact melt and debris. Kupalo, which measures 16 miles (26 kilometers) across and is located at southern mid-latitudes, is named for the Slavic god of vegetation and harvest.

The orbits of planets in the Gliese 581 system are compared to those of our own solar system. The Gliese 581 star has about 30 percent the mass of our Sun, and the outermost planet is closer to its star than the Earth is to the Sun. The 4th planet, G, is a planet that could sustain life.

NASA's Dawn spacecraft viewed this Cerean crater, which is covered in ridges and steep slopes, called scarps on Dec. 23, 2015. Such likely resulted when the crater partly collapsed during its formation. The curvilinear nature of the scarps resembles those on the floor of Rheasilvia, the giant impact crater on Vesta, which Dawn orbited from 2011 to 2012. The 20-mile-wide (32-kilometer-wide) crater is located just west of the larger, named crater Dantu at northern mid-latitudes on Ceres.

Illustration showing the scale and comparative brightness of Pluto’s small satellites. Pluto’s binary companion, Charon, is at the bottom for scale. The image illustrates that two of the moons are highly oblate and that the reflectivity among the moons varies from dark charcoal to the brightness of sand.Hubble can't resolve surface features on the moons so textures are purely for illustration purposes.
