V830 Tau and Its Young World

V830 Tau is a very young star, with an age of 0.002 billion years, and it lies 424 light-years away. Its mass is 1 solar mass, its radius is 2 solar radii, and its temperature is 4250 K. The star's reported radius estimate is larger than the Sun's, while its reported temperature is cooler than the Sun's. One planet is known to orbit this host.

That planet is V830 Tau b, discovered in 2016 by the radial velocity method. The radial velocity method measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. V830 Tau b has a mass of 222 Earth masses and an orbital period of 4.93 days. Its reported mass estimate is larger than Earth's.
