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.
Thus, the Sun occupies 0.00001% (1 part in 10 7) of the volume of a sphere with a radius the size of Earth's orbit, whereas Earth's volume is roughly 1 millionth (10 −6) that of the Sun. Jupiter, the largest planet, is 5.2 AU from the Sun and has a radius of 71,000 km (0.00047 AU; 44,000 mi), whereas the most distant planet, Neptune, is 30 AU ...
Contents. Mercury (planet) Surface temp. Mercury is the first planet from the Sun and the smallest in the Solar System. In English, it is named after the ancient Roman god Mercurius (Mercury), god of commerce and communication, and the messenger of the gods. Mercury is classified as a terrestrial planet, with roughly the same surface gravity as ...
Tenth brightest star in the night sky. [71] Widely recognised as being among the largest known stars, [28] radius decreased to ~500 R ☉ during the 2020 great dimming event. [74] R Horologii: 635 [75] L/T eff: A red giant star with one of the largest ranges in brightness known of stars in the night sky visible to the unaided eye.
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.
The size of the star was obtained using asteroseismology; [7] Kepler-37 is currently the smallest star to be studied using this process. [6] This allowed the size of Kepler-37b to be determined "with extreme accuracy". [6] To date, Kepler-37b is the smallest planet discovered around a main-sequence star [b] outside the Solar System.

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.
Proxima Centauri is the nearest star to Earth after the Sun, located 4.25 light-years away in the southern constellation of Centaurus. This object was discovered in 1915 by Robert Innes. It is a small, low-mass star, too faint to be seen with the naked eye, with an apparent magnitude of 11.13. Its Latin name means the 'nearest [star] of Centaurus'.
