It was discovered by use of the Hubble Space Telescope, and is the smallest of the five known moons of Pluto. It was imaged along with Pluto and Pluto's other moons by the New Horizons spacecraft in July 2015, albeit poorly with only a single image of Styx obtained. [5] Styx is the second-closest known satellite to Pluto, and the fifth discovered.
Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius.

It takes 1.69 years to orbit around Jupiter, and its average distance is 21.01 million km. Jupiter LII has a diameter of about 1 kilometer and in 2010 it was labeled the smallest known moon in the Solar System to have been discovered from Earth. [4] It is a member of the Ananke group. With an estimated diameter of 1 km (0.62 mi), Jupiter LII is ...
Earth has 31 known Moons, one major Moon called Luna, the largest moon of any rocky planet in the Solar System and the largest body typically described as a moon that orbits anything in hydrostatic equilibrium in relation to the primary object by mass and diameter other than Charon and Pluto, the latter two being dwarf planets revolving around ...
Kepler-37b is an exoplanet orbiting the star Kepler-37 in the constellation Lyra. [3] As of February 2013, it is the smallest planet discovered around a main-sequence star, with a radius slightly greater than that of the Moon and slightly smaller than that of Mercury. [4]

Miranda, also designated Uranus V, is the smallest and innermost of Uranus's five round satellites.It was discovered by Gerard Kuiper on 16 February 1948 at McDonald Observatory in Texas, and named after Miranda from William Shakespeare's play The Tempest. [9]
