HD 63433 is a G-type main sequence star with a radius of 0.912 R ☉, a mass of 0.99 M ☉, an effective temperature of 5640 K and a spectral type G5V. [9] Its properties are quite similar to those of the Sun, which has a spectral type G2V and a temperature of 5772 K. [14] Therefore, it is classified as a solar analog. [9]
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 ...
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 ...
From planetary meet-ups to the first total lunar eclipse in three years, here are the top astronomy events to look for throughout 2025: Stellar views of Mars will greet stargazers in January as ...
Below there are lists the nearest stars separated by spectral type. The scope of the list is still restricted to the main sequence spectral types: M, K, F, G, A, B and O. It may be later expanded to other types, such as S, D or C. The Alpha Centauri star system is the closest star system to the Sun.

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 ...
