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]
Jupiter is the fifth planet from the Sun and the largest in the Solar System.It is a gas giant with a mass more than 2.5 times that of all the other planets in the Solar System combined and slightly less than one-thousandth the mass of the Sun. Jupiter orbits the Sun at a distance of 5.20 AU (778.5 Gm), with an orbital period of 11.86 years.
Relative masses of the Solar planets. Jupiter at 71% of the total and Saturn at 21% dominate the system. Relative masses of the solid bodies of the Solar System. Earth at 48% and Venus at 39% dominate. Bodies less massive than Pluto are not visible at this scale. Relative masses of the rounded moons of the Solar System.
Three of the four inner planets (Venus, Earth, and Mars) have atmospheres substantial enough to generate weather; all have impact craters and tectonic surface features, such as rift valleys and volcanoes. [90] Mercury (0.31–0.59 AU from the Sun) [D 6] is the smallest planet in the Solar System.
Jupiter may be best known as the planetary titan of our solar system with a comparatively small red mark — that still dwarfs the entirety of Earth — and rows of striations going from pole to ...
Radius is in the range of 1.2 – 120 km. [3] Disintegrating planetesimal, likely one of several orbiting its star. Likely about one-tenth the mass of Ceres and ~200 km in radius. [5] Smallest known exoplanet. [6] [7] Least massive known exoplanet, at 0.02 Earth masses. Radius estimated from mass-radius relationship. [8]
Most massive planet with a mass of 30 M J, although according to most definitions of planet, it may be too massive to be a planet, and may be a brown dwarf instead. HIP 11915 b ~1 [83] This exoplanet is an analogue to Jupiter, having a similar radius, mass and temperature, and it is orbiting a star analogous to the Sun. Jupiter: 1
Part of a symbiotic binary star system containing a red giant and a white dwarf. As in 2019, with mass 67.54 ± 12.79MJ (0.0523-0.0767 M☉) is the lowest known mass hydrogen-burning star. Luhman 16 B and Luhman 16 A are the closest brown dwarf stars to Earth, and the third-nearest star system to the Solar System.
