NASA's third planet could have found the planet "water world", but it probably does not support life

An exoplanet over three times the earth's size has been found near our solar system.

Key Points:

  • Exoplanet has a surface area of ​​about 150 degrees and is quite nice
  • Scientists do not think life is protected and a gaseous planet or water world & # 39; they could be.
  • NASA is the third exoplanet seen by the TESS space test

NASA's Transpots Exoplanet Survey Satellite (TESS) discovered a mysterious space at the beginning of its mission to scan the planet's new roles and its third discovery in the first three months.

Known to scientists like HD 21749b, the Earth is only 53 light years in the southern constellation Reticulum.

Three times higher is Land, which is classified as sub-Neptune exoplanet, but it is surprising 23 times the mass.

HD 21749b takes 36 days around its star around the orbit, that is, almost the bright Sun.

The new worlds have a surface area of ​​about 150 degrees, according to scientists, it is very pleasant due to its proximity to the star.

Diana Dragomir, directed the discovery of the research index, said that she presented an exciting opportunity for researchers.

"This is the smallest planet we know about this bright star," said Dr Dragomir.

"We know a lot about the atmospheric heat of the planet, but it is very difficult to find smaller orbits that are farther from the star, and thus reflect on these cooler non-planets.

"But here we were lucky, and we caught him and now we can learn more details."

While impressive, it does not seem to be the attributes that the planet planet's life needs to protect itself as a living world.

"The planet has a higher density than Neptune, but it's not rocky," said Dr. Dragomir.

"We believe that this planet would not be gas of Neptune or Uranus, that is, hydrogen and very swelling.

"Water could be a kind of planet or other atmosphere."

It is an exoplanet confirmed by TESS, with Pi Mensae c, roughly twice the size of the Earth and the most eye-popping eye of the Mensa constellation.

The second discovery was the LHS 3884b, which is an orbit near its star, some rocky sides of the day may create pool lava pools.

TESS launched in April of last year to monitor the launch of a two-year mission in the lighting of around 200,000 stars.

The researchers have transmitted comprehensive Earth data to determine the stars that represent the planets passing through the stars.
