Size Comparison of Celestial Objects

Within each picture, size is listed from largest to smallest.

Earth, Venus, Mars, Mercury, the Moon...

Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars, Mercury, the Moon...

Sun (Sol), Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars, Mercury...

Here's the size relation among the smallest stars and the largest members of our solar system...

Arcturus, Pollux (one of "the Twins"), Sirius A, Sun, (Jupiter?)...

Antares, Betelgeuse, Aldebaran, Rigel, Arcturus, Pollux, Sirius A, (Sun?)...

A neutron star is the remnant of the final collapse of an exhausted star more massive than Sol. Here's a neat little comparison of the size of a neutron star. (Remember that Sol has a diameter more than 100 times Earth's.):

Here's another fun comparison - The known "Dwarf Planets" or "Trans-Neptunian Objects" compared with Earth.

Note: Eris and Dysnomia were informally named "Xena" and "Gabrielle" respectively by their discovery team... :-)

This picture came from en.wikipedia.org/wiki/UB313.

This is an artist's conception of a habitable planet around a red dwarf...

Here's a semi-funny factoid about Uranus
