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.

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 ]
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 ancient Hebrews, like all the ancient peoples of the Near East, believed the sky was a solid dome with the Sun, Moon, planets and stars embedded in it. [4] In biblical cosmology, the firmament is the vast solid dome created by God during his creation of the world to divide the primal sea into upper and lower portions so that the dry land could appear.
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]
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.

Vesta and Pallas are nonetheless sometimes considered small terrestrial planets anyway by sources preferring a geophysical definition, because they do share similarities to the rocky planets of the inner solar system. [56] The fourth-largest asteroid, Hygiea (radius 216.5 ± 4 km), is icy.
