The programme has already uncovered a great many worlds. Here are some of the most noteworthy

TOI 700d

TESS’s first Earth-sized world found within the habitable zone. Its orbit is only 37 days long, meaning it’s much closer to its star, however the star is a red dwarf and so much cooler than the Sun.

TOI 270 system

The planetary system TOI 270 has two mini-Neptunes. Planetary scientists will compare them to see how they differ, given both planets formed in the same environment.

Pi Mensae c

The first new planet that TESS discovered back in 2018. It’s around twice the size and five times the mass of Earth, and orbits a Sun-like star once every six days.

TOI 1338

A circumbinary planet, TOI 1338 orbits around a tight binary pair of stars. The planet candidate was initially dismissed, before being spotted by Wolf Cukier, a high school intern working at NASA.

HD 203949b

TESS confirmed that the host star has been through its red giant phase – an event which should have destroyed its planet, which was originally found by Kepler.
