NASA - Transiting Exoplanet Survey Satellite ( TESS ) updates

Amazing to think of 80 Jupiter masses stuffed into one Jupiter diameter whipping around a star three and a half times a week.

It is on the verge of being a Red Dwarf I would have thought.

Thats just edging into the range of "brown dwarfs" -  Y or T class stars.
M dwarfs are much larger than 80-100 jupiter masses.

Actually, Star One is right - 80 Mjup is the top of the brown dwarf mass range and on the lower edge of red dwarf. A brown dwarf can be as small as 13 Mjup.

Thanks I thought my memory had got even worse after reading the other post.

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new hot, bloated "super-Neptune" exoplanet. The newfound alien world, designated TOI-2498 b, is about six times larger and 35 times more massive than the Earth. The finding was published May 16 in Monthly Notices of the Royal Astronomical Society.
