A research team discovered a pair of earth like planets (Teegarden A and Teegarden B) in our galaxy and they’re located in the perfect zone for water to form on their presumably rocky surfaces.
A faint red-dwarf,Teegarden’s star is located just 12.5 light-years away from earth and is comparatively much cooler.
A research team led by the University of Gottingen in Germany announced the Earth-like exoplanet discovery on Tuesday.
“The two planets resemble the inner planets of our solar system,” said Mathias Zechmeister, lead author of a study on the exoplanets in the journal Astronomy & Astrophysics.
“They are only slightly heavier than Earth and are located in the so-called habitable zone, where water can be present in liquid form.”– he added.
The planets are teeny with 9% , the mass of the Sun with a temperature of around 2,900 Kelvin (2,623 Celsius or 4,760 Fahrenheit).
Teegarden’s is the 24th closest star to the Sun. Researchers observed it as part of the larger CARMENES survey for exoplanets, and found evidence for a pair of planets orbiting the star.
According to the paper published in Astronomy and Astrophysics, Teegarden b, has the highest Earth Similarity Index of any planet yet discovered.
“After the first discoveries, now we’re getting the context with these planets,” Guillem Anglada-Escude, astronomer at the Queen Mary University of London
CARMENES is a light spectrum-measuring instrument attached to a 3.5-meter telescope at the the Calar Alto Observatory in Spain that searches for the visible light and infrared signals of exoplanets.
“These studies demonstrate that the signals of the two planets cannot be due to the activity of the star, even though we could not detect the transits of the two new planets,” says astronomer Victor Sánchez Béjar from the Instituto de Astrofísica de Canarias (AIS).
“We are a bit hampered in what we can infer about these planets because we don’t know their radii, but this is a very exciting find, and I hope we will get more observations of this system in the future,” Amy Barr Mlinar, senior scientist at the Planetary Science Institute
