It orbits HD 21749, a K-type star with about 70% of Sun’s mass. It is located 53 light years away from Earth in southern constellation Reticulum.

It is the smallest world outside our solar system that has been identified by TESS so far. Moreover, it is the second planet to be identified by TESS after HD 21749b, a warm “sub-Neptune” with 36-day orbit.</span></span></span></p>

It orbits HD 21749, a K-type star with about 70% of Sun’s mass. It is located 53 light years away from Earth in southern constellation Reticulum. It does not have good life-hosting potential as it circles its host star very tightly and close to it, completing one orbit every 7.8 Earth days, which probably makes it quite hot. </span></span></span></p>

TESS total tally is likely to end up topping that of Kepler has found about 70% of the 4,000 exoplanets discovered to date.</span></span></span></p>

<li style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"><span style="font-family:"Quicksand",serif">It is aimed at searching for exoplanets using transit method in an area 400 times larger than that covered by its predecessor Kepler mission.</span></span></span></li>
<li style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"><span style="font-family:"Quicksand",serif">Its primary mission objective is to survey brightest stars near Earth for transiting exoplanets.
