V830 Tauri is a star located 427 light-years away from the Sun in the constellation Taurus. This star is very young, with an age of only 2 million years, compared to the Sun's age, which is 4.6 billion years. The star has an exoplanet orbiting around it.

Characteristics

V830 Tauri is an M-type star. The star has a mass of roughly 1 solar mass, but has a radius of 2 solar radii, due to the star's age, which means that it hasn't fully contracted yet to become a main-sequence star. It has a surface temperature of. For comparison, the Sun's surface temperature is.
V830 Tauri is a T Tauri star, a pre-main sequence star that has a surrounding disc producing emission lines in its spectrum. It is classified as a weak-lined T Tauri star. It is also classified as a BY Draconis variable, cool stars with starspots and chromospheric activity that vary in brightness as they rotate. The variable period of 2.74 days matches the rotation period.

Planet

On June 20, 2016, an exoplanet was found via radial velocity. It is one of the if not the youngest exoplanet ever found. The exoplanet has a mass of about 0.77 masses of Jupiter and is orbiting away from its host star with a period of and an inclination of.
