The small exoplanet, called L 98-59b, is bigger than Mars, but it's only about 80% 
Earth’s size. Its host star
is an M dwarf about a third the mass of the Sun

TESS Discovers Its Tiniest World To Date
NASA’s TESS space telescope has confirmed the tiniest planet in its catalog so far — one of three discovered around a bright, nearby star called L 98-59.

Two other exoplanets were discovered in the same system (
)
L 98-59c and L 98-59d are about 1.4 and 1.6 times Earth’s size respectively.
So, Discovery Alert! for these guys too!pic.twitter.com/4EZngcyQGQShow this thread -
All of the planets orbit
too close to their star
to be in the "habitable zone.”
They occupy what scientists call the "Venus zone," a range of stellar distances where a planet with an initial Earth-like atmosphere could experience a runaway greenhouse effect

Further study is needed to determine if they have atmospheres
and, if so, which gases are present.
@NASA_TESS will build a catalog of small, rocky planets around nearby stars
for study by the upcoming @NASAWebb space telescope. We can't wait to learn more!pic.twitter.com/GPMSuL0QBk
