Original title: Scientists discover "super land": the neighbors of the solar system are three times more massive than Earth
The 14th British journal Nature published a study in which scientists claimed to have discovered a "super land" in the orbit of a nearby star. How big is this "super land"? Its quality is more than three times that of the earth. How cold is it? Its temperature is about 238 degrees below zero. A super-earth is generally a planet of greater mass than the Earth, but not as big as Neptune and Uranus in the solar system.
Data Map: On July 14, 2015, the NASA New Horizons pluton detector returned a lot of Pluto's most explicit pictures. At this point, the nine brothers of the solar system eventually have a clear picture.
According to reports, the planet and its stars are 30 trillion miles from Earth. Star Barnard is the closest star in our solar system. For decades, astronomers are looking for planets around them. Known as Barnard B, this newly discovered planet is the second known exoplanet from Earth and the fastest star in the night sky.
An exoplanet is a planet outside our solar system. Ignati Ribas, chief scientist at the Spanish Space Science Institute, said in a statement: "After careful analysis, we have 99% confidence that the planet is there." Data from various telescopes around the world This cold and dim world.
"We have used seven different instruments, which cover 20 years of measurement, making it one of the largest and most widely used observations to date," said the scientists.
According to the study, the planet is located in the distant part of a star called "snow line". This far exceeds the zone where there may be liquid water and possible life. It is a barren and cold world and light from the star Barnard represents only 2% of Earth's energy from the sun. Due to its proximity to the Earth, this star has long been a candidate for exoplanets. But the previous search failed to find it.
Astronomer Díaz of the University of Buenos Aires in Argentina said: "This exceptional planet provides critical information to uncover the challenges of planetary formation and evolution."
