The Planet-Hunting TESS Discovers Its Smallest Exoplanet to Date [L 98-59b]
Universe Today ^ | July 3, 2019 | Matt Williams

...one of TESS’ most recent discoveries includes a three-planet system that orbits a star (L 98-59) located roughly 35 light-years from Earth. One of the planets, known as L 98-59b, is between the sizes of Earth and Mars – effectively making it the smallest exoplanet discovered by TESS to date. The discovery also highlights the sophistication of TESS and doubles the number of small exoplanets that are considered worthy of follow-up studies...

While L 98-59b represents a new record for TESS, being about 10% smaller than the previous record-holder it discovered, it is not the smallest exoplanet discovered to date. That record goes to Kepler-37b, a rocky exoplanet located about 210 light-years from Earth that is only about one-third the size of Earth and 20% larger than the Moon.

However, the discovery of L 98-59b is made more impressive when you consider the fact that it orbits an M-type (red dwarf) star that is roughly one-third the size and mass of our Sun. This star is significantly less bright than Kepler-37, which is a G-type (yellow dwarf) star – similar to our Sun – even though L 98-59 is particularly bright as red dwarf goes.

No, calling attention to the stupidity of your statement shows your statement is stupid, and continues to be.

Your ad hominem attack only displays your ignorance.

Your ad hominem attacks are the only ones in this thread. Crack a book sometime.

Is the issue finding somewhere to go or finding a way to get there? I think I’m on to something.
