Original title: Scientists Reveal "Super Earth": Neighbors of Solar Networks are 3 times more massive than Earth
BEIJING, November 15 (Xinhuanet) – On November 14, the British newspaper Nature published a study in which scientists claimed to have discovered a "super country" in the orbit of a nearby star. What is this "super country"? Its quality is more than three times the size of the earth. How cold is it? Its temperature is about 238 degrees below zero. The Earth is mostly a planet of greater mass than Earth, but not as large as Neptune and Uranus in the Solar System.
Data Map: July 14, 2015, NASA Pluto Detector Nev Horizons returned a series of the smallest photos of Pluto. At this moment, the nine brothers of the solar system finally have a clear picture.
According to reports, the planet and its stars are 30 trillion miles from Earth. Barnard's star is the closest star to our solar system. Absolutely for decades, astronomers have been searching for planets around them. Known as Barnard B, this newly discovered planet is another known exoplanet from Earth and the fastest star on the night sky.
Ekoplanet is a planet outside of our solar system. Ignati Ribas, chief scientist at the Spanish Institute for Space Science, said in a statement: "After a careful analysis, we have 99% security that the planet is there." Data from various telescopes around the world This cool and dark world.
"We used seven different instruments, covering 20 years of measurement, making it one of the largest and most widely used observations to date," scientists say.
According to the study, the planet is located in the distant part of a star called the "snow line". This goes far beyond the area where one can live where liquid water can be present and a possible lifespan. It's a steady and cold world, and the brightness of Barnard's star makes up only 2% of Earth's energy from the sun. Because of its proximity to the Earth, this star has long been a candidate for finding exoplanets. But the previous search failed to find her.
Astronomer Diaz University of Buenos Aires, Argentina, said: "This extraordinary planet provides us with vital information to discover the challenges of planetary formation and evolution."
