Scientists confirmed the existence of HD 20794 D. This super-world is in the livable area for 647 days.
This region expresses a distance in which liquid water may exist. This invention, which was obtained with more than 20 years of observations, opens the door to examining the new generation of telescopes and planet atmosphere.
The Canary Islands Astrophysics Institute (IAC) and the University of La Laguna (ULL) confirmed the discovery of a super-world around the Sun-like stars called HD 20794.
This invention provides a valuable opportunity to obtain with more than 20 years of observations, allowing more detailed examination of the atmosphere of world -like planets.
Searching for planets in livable areas of sun -like stars is an important step to understand the possibility of extraterrestrial life.
In addition, this discovery provides critical information for scientists who investigate how life is formed on our planet.
The HD 20794 is slightly smaller than the Sun and is only 20 light years away. This discovery was the third discovery after two other super-world discovered in the same system for more than 10 years ago.
Super-world in the livable area
The newly discovered planet HD 20794 D is a super-world six times heavier than Earth. He takes a tour around his star every 647 days; This is about 40 days shorter than the time when Mars revolves around the sun.
This orbit places the planet in the livable area of the star of the star, that is, on the surface is located at a distance of liquid water. This is one of the basic components necessary for the life we know.
The distance to the planet’s star and the proximity of the system makes it especially attractive. These features make ELT, ESO’s 40 -meter telescope or ESA and NASA’s excellent candidate for observations with future space missions.
Although the planet is located in the livable area of the system, it is yet too early to tell you whether it can accommodate life.
High mass and eccentric orbit makes it a very different planet from our world.
Unlike most planets in the Solar System, the orbit of the HD 20794 D is not circular, but elliptical. His distance to his star changes significantly, which causes the planet to move from the outer edge of the livable area to the inside of the planet.
