NASA images showed looming giant asteroid to Earth
The researchers showed the first images of the giant asteroid 2015 TB145, closing in on Earth. This facility opened American automatic Pan-STARRS on Hawaii, and the first of his pictures received in the Arecibo Observatory in Puerto Rico. This was reported on the NASA website.
Upon receipt of the images, scientists have noticed in the middle of the dark areas of the asteroid, which, according to the astronomers, may be followed by an impact crater. Total October 30 were obtained six radar images of the asteroid. The resolution of images is equal to 7.5 meters per pixel.
With the radar system, astronomers know the parameters of the asteroid. The diameter of the celestial body reaches 600 meters (ten times larger than the Tunguska body), significantly more than previously thought. Asteroid makes a complete revolution around its axis in five hours and is directed toward the planet at a speed of 35 kilometers per second.
It is expected that at about 20:00 Moscow time a celestial body would be at a distance of 486,000 kilometers from the Earth's surface (1.3 times greater than the distance to the Moon). The asteroid will be visible from Russia (assuming clear sky) using binoculars or an amateur telescope. To distinguish the object from the other celestial objects can be in its movement across the sky in the constellation Ursa Major.
Asteroid 2015 TB145 opened October 10th Pan-STARRS system and is classified as a potentially dangerous object (because of its size and proximity to Earth). These objects include body sizes greater than 100 meters and are approaching the planet at a distance of 7.5 million kilometers.
The next time an asteroid close to Earth will be in September 2018 at a distance of 38 million kilometers (this is approximately a quarter of the distance between the planet and the Sun). Over the next 100 years, it is not harmful to the planet.
