About LHS 475 b

  • Researchers have labelled the new exoplanet as LHS 475 b, and it’s roughly the same size as Earth, the agency added.
  • It is located just 41 light-years away, the planet orbits very close to a red dwarf star and completes a full orbit in just two days.

What are Exoplanets?

  • These are planets that orbit other stars and are beyond our solar system.
  • Exoplanets come in a host of different sizes. They can be gas giants bigger than Jupiter or as small and rocky as Earth. 
  • They are also known to have different kinds of temperatures; boiling to cold.
  • Scientists rely on indirect methods to discover exoplanets such as the transit method, which is “measuring the dimming of a star that happens to have a planet pass in front of it”
  • Scientists believe that there are more planets than stars as each star has at least one planet orbiting it.
  • Studying exoplanets not only broadens our understanding of other solar systems but also helps us piece together information about our planetary system and origin
