Scientists have discovered the most earth-like exoplanet

The CARMENES Surveying Team, a huge group of international astronomers, is looking for exoplanets near the habitable zones of distant stars. You may have just discovered the most earthly planet out there.

Exoplanet discoveries are occurring all the time – there are an estimated hundreds of billions of planets throughout the universe.

However, this particular planet has caught the attention of how much it may resemble the Earth.


The 24th next star. and relatively quiet ultra-cool star. It is the 24th star closest to the sun.

The search for such potentially habitable planets provides clues as to where we might find extraterrestrial life. Although it is an exciting finding, it does not necessarily mean that humans could survive there.

Two planets

The researchers actually found two planets orbiting around Teegarden's star ̵

1; they are called Teegarden b and Teegarden c. [19659010] Teegarden b is the one most similar to Earth. According to the published article, the planet has the highest Earth similarity index of all planets ever discovered – the planet scored 0.94, with 1.0 indicating a perfect Earth model.

They also underline the fact that the index "does not take into account the spectral energy distribution of the star and the resulting composition of the atmosphere, which is very likely to affect the habitability."

The two planets were discovered from the Spanish Calar Alto Observatory.

Teegarden's star itself is actually a tenth the size of the Sun, although the planets orbit close enough (they are in the habitable zone) to maintain a temperate environment similar to Earth's, the researchers claim.

Researchers have discovered that Teegarden b and c are in the star's life zone, but there is more to learn. For example, they do not yet know the size of the planets.

"We're a bit handicapped about what we can do about these planets because we do not know their radii," said Planetary Science Institute scientist Amy Barr Mlinar Gizmodo

"But this is a lot exciting find, and I hope that in the future we will get more observations of this system. "

Further observations and analysis could help us to find out if Teegarden b is habitable for future settlers.
