Nov 9, 2022 · Astronomers have been classifying and categorizing the objects in the sky for thousands of years: planets (originally including the Sun and Moon), stars, meteors, and comets.

Celestial Bodies. Halley’s Comet. Neptune. Venus. Moon. Solar System. By the definition, a celestial body is a natural object outside of the Earth's atmosphere. For examples, Moon, Sun, and the other planets of our solar system. But, actually, these are very partial examples.
There are four main categories of classifications when determining the type of celestial body an object is. These classifications are: terrestrial planets (Mercury, Venus, Earth, and Mars), gas giants (Jupiter and Saturn), ice giants (Uranus and Neptune), and dwarf planets (Pluto, Eris, Haumea, and Makemake). Ceres at this current time is still ...
