Its “name” is 2015 TB145, has a diameter of about 500 meters and will be visible from Italy. especially the night before rapprochement. “There’s no danger of impact with our planet because the distance is safe,” says astrophysicist Gianluca Masi, head of the Virtual Telescope. But, he adds, will be an excellent opportunity to closely observe this asteroid.
According to NASA should be one of the best radar targets for this year and were scheduled observations with telescopes Green Bank and Arecibo. For another flyby of a known object of this size, underlines the American space agency, will have to wait until 2027, when it will pass the asteroid 1999 AN10.
“It will be an important approach – detects Masi – when the minimum distance from Earth, the asteroid will be very bright, it has a magnitude 10, ie the range of binoculars and a small amateur telescope. ” However Italy, adds, October 31 observation will not be easy, because the object is very low on the horizon and we will be the light of the moon that will bulky recently passed the stage full (Oct. 27). There will be better conditions the night before the closest approach, ie between 30 and 31 October, ‘when? explains astrophysicist – the brightness of the asteroid will be 12 mag, but the reach of a good amateur telescope also of diameter between 15-20 centimeters. ” You can groped observation after 23.00, continues Masi, when TB145 2015 will be among the stars of the constellation Orion. The only problem, says, “could be the Moon will still be very bright.”
