New observations from Keck Telescope confirm mass of scorching Earth-sized planet TOI 6324 b

Star system: G 264-17 | Distance from the Sun: 67.1 light years

It’s the closest confirmed ultra-short-period planet to Earth’s size, with no thick atmosphere. The planet TOI 6324 b orbits a nearby (67 light years) red dwarf star with about 20 % solar mass. The planet's orbit is so tight, that the year on it lasts less than a day. Although the planet is similar in size and mass to Earth, its proximity to the star expose it to extreme temperature and radiation.
