TrES-1b
Sign in to saveAlso known as NAME V672 Lyr b, TOI-1236b, TOI-1236.01, TIC 120757718b
TrES-1b is an extrasolar planet approximately 523 light-years away in the constellation of Lyra (the Lyre). The planet's mass and radius indicate that it is a Jovian planet with a similar bulk composition to Jupiter. Unlike Jupiter, but similar to many other planets detected around other stars, TrES-1 is located very close to its star, and belongs to the class of planets known as hot Jupiters. The planet was discovered orbiting around GSC 02652-01324 (an orange dwarf star).

TrES-1b is an extrasolar planet approximately 523 light-years away in the constellation of Lyra (the Lyre). The planet's mass and radius indicate that it is a Jovian planet with a similar bulk composition to Jupiter. Unlike Jupiter, but similar to many other planets detected around other stars, TrES-1 is located very close to its star, and belongs to the class of planets known as hot Jupiters. The planet was discovered orbiting around GSC 02652-01324 (an orange dwarf star).
==Detection and discovery== TrES-1b was discovered by the Trans-Atlantic Exoplanet Survey by detecting the transit of the planet across its parent star using a telescope. The discovery was confirmed by the Keck Observatory using the radial velocity method, which allowed its mass to be determined.
