The planet, called L 98-59b, marks the smallest found by TESS yet. <\/p>\n<p>Two other worlds orbit the same star. While all three planets&#8217; sizes are known, further study with other telescopes will be needed to determine if they have atmospheres and, if so, which gases are present. The L 98-59 worlds nearly double the number of small exoplanets &#8212; that is, planets beyond our solar system &#8212; that have the best potential for this kind of follow-up. <\/p>\n<p>L 98-59b is around 80 Earth&#8217;s size and about 10 smaller than the previous record holder discovered by TESS. Its host star, L 98-59, is an M dwarf about one-third the mass of the Sun and lies about 35 light-years away in the southern constellation Volans. While L 98-59b is a record for TESS, even smaller planets have been discovered in data collected by NASA&#8217;s Kepler satellite, including Kepler-37b, which is only 20 larger than the Moon. <\/p>\n<p>The two other worlds in the system, L 98-59c and L 98-59d, are respectively around 1.4 and 1.6 times Earth&#8217;s size. All three were discovered by TESS using transits, periodic dips in the star&#8217;s brightness caused when each planet passes in front of it. <\/p>\n<p>Video Credit: NASA&#8217;s Goddard Space Flight Center\/Chris Smith (USRA): producer and lead animator\/Jeanette Kazmierczak (UMCP): Science Writer <\/p>\n<p class=\"MsoNormal\" style=\"margin: 5px;\">&nbsp;<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>NASA&#8217;s Transiting Exoplanet Survey Satellite (TESS) has discovered a world between the sizes of Mars and Earth orbiting a bright, cool, nearby star.
