Illustration of the exoplanet LHS 3844 b. It is a rocky planet about 1.3 times Earth’s size located about 49 light-years away in the constellation Indus, making it among the closest transiting exoplanets known. The star is a cool M-type dwarf star about one-fifth the size of our Sun. Completing an orbit every 11 hours, the planet lies so close to its star that some of its rocky surface on the daytime side may form pools of molten lava.

Illustration of the exoplanet Pi Mensae c. The planet is about twice Earth’s size. Every six days, the new planet orbits the star Pi Mensae, located about 60 light-years away and visible to the unaided eye in the southern constellation Mensa. The bright star Pi Mensae is similar to the Sun in mass and size.

Exoplanet HD 21749 c Animation
Read moreThis animation shows HD 21749 c, an exoplanet about 89% Earth’s diameter. It orbits HD 21749, a K-type star with about 70% of the Sun’s mass located 53 light-years away in the southern constellation Reticulum. A second, bluish exoplanet in the same system, HD 21749 b, appears briefly in the background.Credit: NASA/JPL-Caltech/R. Hurt (IPAC) || NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered its first Earth-size world, named HD 21749 c. It’s about 89% of Earth’s size and orbits HD 21749, a K-type star with about 70% of the Sun’s mass located 53 light-years away in the southern constellation Reticulum, and is the second planet TESS has identified in the system. The new world is likely rocky and circles very close to its star, completing one orbit in just under eight days. The planet’s surface is likely very hot, with temperatures perhaps as high as 800 F (427 C). HD 21749 c's host star is bright and relatively nearby, and is therefore well suited to more detailed follow-up studies, which could provide critical information about the planet’s properties. ||
