Find the closest Solar System Planet Earth – 11/15/2018

Our neighbors are "cold and dark" in the solar system. In 2016, the discovery of a proxima similar to the Earth's orbital orbits, the magazine's arrival Nature. Two years later, this publication enters into a new discovery: a Superbaraja It is about 3.2 times the size of Earth and the Bernard Origins.

The second closest is the next B, which is It's six light years away.

The discovery was one of the largest international monitoring campaigns in history. Telescopes around the world took about 800 mile. "More than 20 years have been collected by the Ignatius Rebas International of Space Studies of Catalonia (IEEC-CSIC), an international partnership.

"All of these data allowed us to shape the Bernard's orbit," the next second,We do not rule out more planets"Says the researcher.

But how is this system The newly discovered planet is based on a star named Barnard, a red dwarf between 7,000 to 10,000 million years, "twice as much as the sun", a relatively inactive and fastest night in the night sky.

Bernard BHis hostess will take 233 days to get baptized in honor of his host, and it is very close (40% from the Tierra del Sol), which is a "cold dark world" and "they describe it, it's -170 degrees.

"This is a frozen world, because only a few epochs of energy are obtained from its star: only two percent of the planet's surface comes from the sun." The unstable compounds such as water near the star's known "ice line" are buried in solid ice.

To that end, The liquid water on the surface of Bernard Bick is very "unusual", But you can not threaten that it is in the soil, explains Reebs.

In addition, it is considered to be the best potential for life outside the solar system compared to proximity. Any life on earth does not seem to contain any kind of animal, but "finds life-ways in life," warns the Spanish physicist.

These findings are possible for Doppler techniques. This is one of many ways for astronomers to find planets that are impossible to direct.

When a planet orbits a star, the gravitational pull of the planet causes the star to cause its star because it affects the motion of the star.

"According to physics, when a light source approaches the observer, the spectrum is slightly smaller into the blue and the wavelength of its wavelength diminishes when it moves in red and it reaches the rectum.As the star passes through a star, I realized there was a planet, "Ribas points out.

Red Dots, who searches for planets next to the solar system, thanks to the high precision measurements of telescopes across the globe from the discovery of the exponent of the Carmen's project.

These are the European Southern Observatory (ESOs), known as the Planet Planets and Yuen Spectroscopy.

"Harpas played a significant role with the information collected from other teams, including the new and overlapping dimensions of the Bernard's star from various projects," says Guillaal Anglata Esquado of Queen Mary University, London.

"The combination of results was crucial to stabilizing our results", the Spanish language astronomer emphasizes, and led some of the proxima B discoveries a few years ago.

Harps, a change in the speed of a star that is orbiting an orbit, can detect speed limits in a 3.5 km speed (the rate at which it is used).

Observations from seven different devices have been collected with accurate 771 measurements of 20 years, according to Ribas, "huge" information.

"What a discovery a Significant advances in solar exploration The co-author of the Andulusia Institute of Astrophysics and co-author of Cristina Rodríguez-Lopes, "Our staller was surrounded by neighbors to find someone with the right situation to keep their lives alive.

She co-authored the study of scientists from Spain, Chile, China, France, Germany, Israel, Poland, Switzerland, the United States and Britain.
