The size of solid bodies does not include an object's atmosphere. For example, Titan looks bigger than Ganymede, but its solid body is smaller. For the giant planets , the "radius" is defined as the distance from the center at which the atmosphere reaches 1 bar of atmospheric pressure.

Diagram of the Milky Way, with galactic features and the relative position of the Solar System labeled. The Solar System is located in the Milky Way , a barred spiral galaxy with a diameter of about 100,000 light-years containing more than 100 billion stars. [ 269 ]
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.
It's a mind-blowing sequence. The viewer is invited to reflect on stars so large their size strains the limits of comprehension. It's a high resolution, accurate and thought-provoking image - certainly a worthy candidate.

The Sun, planets, moons and dwarf planets (true color, size to scale, distances not to scale) The following outline is provided as an overview of and topical guide to the Solar System: Solar System – gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the ...
A fossorial animal (from Latin fossor 'digger') is one that is adapted to digging and which lives primarily (but not solely) underground. Examples of fossorial vertebrates are badgers , naked mole-rats , meerkats , armadillos , wombats , and mole salamanders . [ 1 ]
Each star follows an evolutionary track across this diagram. If this track takes the star through a region containing an intrinsic variable type, then its physical properties can cause it to become a variable star. An example of this is the instability strip, a region of the H-R diagram that includes Delta Scuti, RR Lyrae and Cepheid variables. [7]
