Near-Earth asteroids come in a whole range of sizes, from massive 41-km-wide 1036 Ganymed down to ones just a few metres wide. The orbits of all the near-Earth asteroids are shown here in relation to the orbits of the inner planets....
Depending on the star's distance from Earth, ALMA was able to distinguish features as small as a few Astronomical Units. (An Astronomical Unit is the average distance of the Earth to the Sun—about 150 million kilometers, which is a useful scale for measuring distances on the scale of star...

and Uranus in turn is nearly twice as far from the sun as Saturn. What this implies is that when considering distances from Earth to its planetary neighbors, moving from one to the next is not like walking along a city street and encountering a series of regularly spaced intersections. Inste...
5A). Arguably the best-known asteroids comprise the main asteroid belt between Mars and Jupiter, but other groups include those that orbit the Sun at distances between Jupiter and Neptune, and in the region of space through which Earth passes. Comets are irregular objects made up of a mix ...

The free-floatinggiant planetshad a different history in that they were probably formed in circumstellar disks but were ejected from their solar systems through...
