Dwarf Planet Ceres is the largest object in the asteroid belt that lies between the orbits of Mars and Jupiter. Its diameter is approximately 945 kilometres, making it the largest of the minor planets within the orbit of Neptune. The 33rd-largest known body in the Solar System, it is the only dwarf planet within the orbit of Neptune.

Phobos is the innermost and larger of the two natural satellites of Mars, the other being Deimos. Both moons were discovered in 1877 by American astronomer Asaph Hall.

Russia sent two probes to view Phobos and they were knocked out of orbit by a long cigar shaped cylinder like object which they took a picture of before the second ship. It is thought that maybe Deimos and Phobos are artificial objects that don’t belong in the skies above Mars it is believed that both moons could be hollow.
