10 Tauri is a star

Star

A star is a massive, luminous sphere of plasma held together by gravity. At the end of its lifetime, a star can also contain a proportion of degenerate matter. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth...

, it is slightly more massive and luminous than the Sun, and about the same age or older. Spectral classification places it between a dwarf and sub-giant, so it appears to be a well-evolved star that may be near the end of its time on the main sequence

Main sequence

The main sequence is a continuous and distinctive band of stars that appears on plots of stellar color versus brightness. These color-magnitude plots are known as Hertzsprung–Russell diagrams after their co-developers, Ejnar Hertzsprung and Henry Norris Russell...

. It is a suspected spectroscopic binary, although this has not been confirmed. When viewed through a telescope, there is also a line-of-sight companion.

A debris disk has been identified around 10 Tauri, based on excess infrared radiation detected by IRAS/ISO.
