The graphic shows all the planets and moons seen in the original (theatrical) trilogy to scale alongside the two Death Stars for good measure. The sizes of the various bodies as found on http://starwars.wikia.com/ are: NameDiameterType Tatooine 10,465 km Planet Alderaan 12,500 km Planet...
Related to Planet formation:Herbig Ae-Be stars nebular hypothesis n. A hypothesis concerning the formation of stars and planets, and therefore the origin of the solar system, according to which a rotating nebula underwent gravitational collapse into a star with an accretion disk, from which planets...
Pluto so that the two planets remain in orbits that cross, Pluto has not cleared its own orbit and was therefore demoted from planet status to that of a newly created category,dwarf planet.Like a planet, a dwarf planet orbits the sun, is large enough to assume a nearly round shape, and...

Astronomy deals with big things. Big objects such as planets and stars, and big distances. This lesson deals with the planetary scale of measurement, and how extremely distant objects are observed. From the Moon to the Edge of the Observable Universe ...

Here we present a simulation of interstellar turbulence with a grid resolution of 10,0483 cells that allows us to determine the position and width of the sonic scale (ℓs)—the transition from supersonic to subsonic turbulence. The simulation simultaneously resolves the supersonic and subsonic ...
star with respect to 6 to 8 distant reference stars in the micro-arcsecond-level scale, thus evaluating the tiny wobble of the target star caused by the gravitational disturbance from its orbiting planets, and detecting Earth-like planets in the habitable zone around the nearby Sun-like stars....
