Proxima Centauri is a red dwarf star with a mass about 12.5% of the Sun's mass (M ☉), and average density about 33 times that of the Sun. Because of Proxima Centauri's proximity to Earth, its angular diameter can be measured directly. Its actual diameter is about one-seventh (14%) the diameter of the Sun.
The scale model of Proxima Centauri in Yulara, Australia. In 2018 scale model of the star Proxima Centauri was added to Akaa Solar System Scale Model. Proxima Centauri is a red dwarf star and the nearest star to the Solar System. It is located 4.24 light-years away.
These lists contain the Sun, the planets, dwarf planets, many of the larger small Solar System bodies (which includes the asteroids), all named natural satellites, and a number of smaller objects of historical or scientific interest, such as comets and near-Earth objects.
