Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius.
Like it better than the planet sizes pic, actually. Ceran thor 01:34, 20 February 2009 (UTC) Support - A remarkable image; it serves as a dramatic and accessible showcase of the differing scales of objects in our universe, even before we approach the galactic scale. Furthermore, most of the comments previously raised seem to have been addressed.
It's a mind-blowing sequence. The viewer is invited to reflect on stars so large their size strains the limits of comprehension. Creator Dave Jarvis Nominated by StevenJohnston 21:12, 10 February 2009 (UTC) Comments. In general, it really is a nice, easy to understand comparison, but I have three concerns.

The sizes are listed in units of Jupiter radii (R J, 71 492 km).This list is designed to include all planets that are larger than 1.7 times the size of Jupiter.Some well-known planets that are smaller than 1.7 R J (19.055 R 🜨 or 121 536.4 km) have been included for the sake of comparison.
The smallest of these, Kepler-42d, is about the size of Mars with a radius of only 0.57 times that of Earth. Not long ago, in Dec. of 2011, the Kepler team announced the discovery of Kepler-20e and Kepler-20f -- the first Earth-size planets ever found outside the solar system.
Approximate sizes of the planets relative to each other. Outward from the Sun, the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Jupiter's diameter is about 11 times that of the Earth's and the Sun's diameter is about 10 times Jupiter's. The planets are not shown at the appropriate distance from the Sun.
