The sizes are listed in units of Jupiter radii (71,492 km). All planets listed are larger than 1.7 times the size of the largest planet in the Solar System, Jupiter. Some planets that are smaller than 1.7 RJ have been included for the sake of comparison.
There are about 51 galaxies in the Local Group (see list of nearest galaxies for a complete list), on the order of 100,000 in the Local Supercluster, and an estimated 100 billion in all of the observable universe. [1]

Lists of planets These are lists of planets. A planet is a large, rounded astronomical body that is neither a star nor its remnant. The best available theory of planet formation is the nebular hypothesis, which posits that an interstellar cloud collapses out of a nebula to create a young protostar orbited by a protoplanetary disk. There are eight planets within the Solar System; planets ...
This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses ( M☉ ), approximately 2×1030kilograms .
List of coolest exoplanets This is a list of the coolest exoplanets known, specifically those with temperatures lower than −75 °C (198 K). Planets from the Solar System were also included for comparison purposes.
