The regions with higher density of stars are shown; these correspond with known star clusters (Hyades and Coma Berenices) and moving groups. This is a list of nearby stellar associations and moving groups. A stellar association is a very loose star cluster, looser than an open cluster. A moving group is the remnant of such a stellar association ...
The closest encounter to the Sun so far predicted is the low-mass orange dwarf star Gliese 710 / HIP 89825 with roughly 60% the mass of the Sun. [4] It is currently predicted to pass 0.1696 ± 0.0065 ly (10 635 ± 500 au) from the Sun in 1.290 ± 0.04 million years from the present, close enough to significantly disturb the Solar System's Oort ...
These are in addition to 8 new star systems announced between 2000 and 2005. [4] RECONS is listed explicitly as an author on papers submitted to the Bulletin of the American Astronomical Society since 2004. [5] The RECONS web page includes the frequently referenced "List of the 100 nearest star systems". [6] They update this list as discoveries ...

Some of the brightest stars in the night sky, such as Rigel and Antares, are in the list. While supergiants are typically defined as stars with luminosity classes Ia, Iab or Ib, other definitions exist, such as those based on stellar evolution. [1] Therefore, stars with other luminosity classes can sometimes be considered supergiants.
Gliese 710, or HIP 89825, is an orange 0.6 M ☉ star in the constellation Serpens Cauda. It is projected to pass near the Sun in about 1.29 million years at a predicted minimum distance of 0.051 parsecs—0.1663 light-years (10,520 astronomical units) [5] (about 1.6 trillion km)—about 1/25th of the current distance to Proxima Centauri.

The million-year-old star at the center of the disk has a temperature of 3,000 K and is emitting 0.4 times the luminosity of the Sun. [ 12 ] The 2023 NASA / ESA / CSA James Webb Space Telescope image—released on the telescope's first anniversary—shows young stars, roughly the size of the Sun, at the center of circumstellar discs.
