It's been a year since NASA's planet-hunting TESS satellite began searching our southern skies for distant exoplanets, and it's made quite a few interesting finds.
The three are missing links of sorts. One of the scientists behind the discovery said the planets "straddle a well-established gap" in known planet sizes.
All three orbit a star about 73 light-years away — relatively close by interstellar standards. One of the planets is a super-Earth — a large rocky planet — and the other two NASA calls mini-Neptunes.
The satellite still has a lot of work to do. With its first year under its metaphorical belt, it will shift its search to stars in our northern hemisphere for more exoplanets.
