description Teegarden's Star c Overview
Teegarden's Star c is a confirmed planet orbiting the nearby ultracool red dwarf known as Teegarden's Star. It was announced in 2019 with Teegarden's Star b after the planets were detected through periodic changes in the star's radial velocity. With a mass close to Earth's and an orbital period of about 11.4 days, it receives less stellar energy than planet b and is discussed in connection with the outer part of the system's potentially temperate region.
help Teegarden's Star c FAQ
What is Teegarden's Star c?
Teegarden's Star c is a confirmed planet orbiting the nearby ultracool red dwarf called Teegarden's Star. It was announced in 2019 together with Teegarden's Star b.
How was Teegarden's Star c detected?
The planets were detected through periodic changes in the star's radial velocity. This method tracks the star's motion as the planets' gravity pulls on it.
Is Teegarden's Star c similar in mass to Earth?
Its mass is close to Earth's according to the supplied description. That makes it a terrestrial-mass planet, although mass alone does not prove that its surface is Earth-like.
Does Teegarden's Star c transit its star?
The discovery was based on radial-velocity changes rather than a reported transit. A radial-velocity detection measures the star's motion instead of a dip in starlight.
