The National Aeronautics and Space Administration (NASA) of USA has discovered a new planet.
NASA Discovers New Planet
  • It is the third new planet discovered by the NASA mission- Transiting Exoplanet Survey Satellite (TESS).

About the New Planet- HD 21749b:

  • The new planet HD 21749b is outside our solar system and orbits a dwarf star 53 light years away.
  • HD 21749b orbits a bright star in the constellation Reticulum.
  • It has the longest orbital period of all the three discoveries made by TESS.
  • It is predicted that the surface of the new planet is likely around 300 degrees Fahrenheit, which is relatively cool, given its proximity to its star,which is almost as bright as the Sun.

Other planets discovered by TESS:

  • The other two discoveries made by the TESS probe are Pi Mensae b and LHS 3844b. 
  • Pi Mensae b has an orbit of 6.3 days and LHS 3844b has an orbit of just 11 hours.

About the TESS Mission:

  • The Transiting Exoplanet Survey Satellite (TESS) mission of NASA is an explorer mission which is undertaking an all-sky survey to search for planets transiting nearby stars. 
  • The objective of the TESS mission is to discover planets smaller than Neptune that transit stars bright enough to enable follow-up spectroscopic observations that can provide planet masses and atmospheric compositions.

Question:

Q. A third new planet is discovered by which mission of NASA?
a. Transiting Exoplanet Survey Satellite (TESS) Mission
b. Orbiting Exoplanet Survey Satellite (OESS) Mission
c. Revolving Exoplanet Survey Satellite (RESS) Mission
