TOI-6002 b: Habitable Zone, 11-Day Year
Super-earth around TOI-6002
It is 1.65 times Earth's radius, closest in size to Earth. A year there lasts 10.90 days, on an orbit 7 times closer to its star than Mercury is to the Sun. Its equilibrium temperature is 321 K, hotter than any desert. The host star TOI-6002 runs at 3229 K with 0.21 times the Sun's mass.

Inside the habitable zone, computed from the star's luminosity. Yes.
A measured mass, not just a radius. No.

What a crossing measures
How deep the star dims fixes the planet's size relative to it.
Found by Transiting Exoplanet Survey Satellite (TESS) in 2024. TESS scans most of the sky in 27-day stretches, so it favours bright nearby stars and short orbits over the faint distant ones Kepler specialised in.
Found by watching its star dim as it crossed in front. That measures size and not weight, which is why there is a radius here and no mass.
TOI-6002 b sits in the habitable zone on the arithmetic alone. That says where \
it orbits, not what it is like. What would you want measured next before calling it promising?
