SUMMARY

Astronomers have identified a potentially habitable exoplanet named Teegarden b orbiting Teegarden's Star, located 12 light-years away in the Aries constellation. Teegarden b has a minimum mass nearly identical to Earth and resides within the star's habitable zone, presenting a 60% probability of possessing a temperate surface environment. The estimated surface temperature is approximately 28°C, assuming a terrestrial-like atmosphere. Teegarden b boasts the highest Earth Similarity Index of 95%, indicating its close resemblance to Earth in terms of mass and insolation.

PREREQUISITES
  • Understanding of exoplanetary science
  • Familiarity with the concept of habitable zones
  • Knowledge of the Earth Similarity Index
  • Basic astronomy, particularly regarding red dwarf stars
NEXT STEPS
  • Research the characteristics of red dwarf stars and their habitable zones
  • Explore the methods used to calculate the Earth Similarity Index
  • Investigate the implications of temperate surface environments on potential life
  • Learn about the techniques for detecting exoplanets, such as the transit method
USEFUL FOR

Astronomers, astrobiologists, and anyone interested in the search for habitable exoplanets and the conditions necessary for life beyond Earth.

Astronomers have discovered a potentially habitable exoplanet around Teegarden's Star.

Teegarden is an old red dwarf star 12 light-years away in the Aries constellation.

The exoplanet found, called Teegarden b, has a minimum mass almost identical to Earth.

It orbits within the star's habitable zone.

And it has a 60% chance of having a temperate surface environment.

Surface temperature should be closer to 28°C assuming a similar terrestrial atmosphere.

Teegarden b is the exoplanet with the highest Earth Similarity Index discovered so far: 95%.

This means that it has the closest mass and insolation to terrestrial values.
