Astronomy: Barnard's arrow has a planet



After the Alpha Centauri, the Bernard's Erro star is the closest nearest star to the Earth. Astronomers could now find a planet in more than 20 years of observation data. Every 226 days will travel 60 million km and there will be a three-pointed star on the earth and a circle around it.

Although the planet is closer to his star than 150 million miles from the Sun, the planet must be an ice world. Barnard's elliptical star is a red dwarf that has only one-sixth of the Sun's mass. The planet is located near the glacier area of ​​the star. The low temperatures are -100 ° C and ammoniaces remain in vain.

Before the planets were discovered outside our solar system, the region was considered a priority area for the formation of planets around a star. Finally, all gases from the internal gases of the region's core, like solid snow, become the foundation for stronger bodies.

Since the planet does not move to the front of the star, astronomers use radial speed techniques as measurements. The signal is very weak and can not be traced back to previous dimensions. The two-year surveillance campaign and the combined data of the past 20 years have provided enough protection.

The information was more unusual, suggesting a planet of 6,600-day orbit and 15 times the Earth's orbit. There is not enough confirmation as in previous information. But in the orbit of Barnard's star it is possible to change the star's position that the planet can be altered by the measurements of gravitation. This cycle may take some time, since it is a cycle of twenty years.

Barnard's Asro Star is no doubt a planet. One of the closest neighbors of the Sun, from the beginning, is a goal to prove the planets. In the 1960s, Dutch astronomer Peter van der Kamp believed that the constant star was caused by a planet. Several teams have been reviewed and rejected by a discovery. Ultimately, the permanent management of the telescope became the source of measurements.

When Edward Barnard finds a measurement in 1916, it moves very fast when compared to other stars in the sky. A half-hour diameter was discovered in the sky with its own motion of approximately 10 arc seconds per year.
