What is the closest asteroid?

The smallest known near-Earth asteroid is 2008 TS26 with an absolute magnitude of 33.2, corresponding to a diameter of about 1 m (3.3 ft). The largest such object is 1036 Ganymed, with an absolute magnitude of 9.45 and a directly measured diameter of about 38 km (24 mi).Click to see full answer. Then, what is the closest asteroid to hitting Earth? Timeline of known close approaches less than one lunar distance from Earth Date of closest approach Date discovered Object 2019-05-28 2019-05-26 2019 KT 2019-06-06 2019-06-06 2019 LY4 2019-06-08 2019-06-02 2019 LW4 2019-06-22 2019-06-22 2019 MO One may also ask, when was the last time an asteroid hit the earth? The last known impact of an object of 10 km (6 mi) or more in diameter was at the Cretaceous–Paleogene extinction event 66 million years ago. The energy released by an impactor depends on diameter, density, velocity, and angle. Beside this, where is the asteroid? The vast majority of known asteroids orbit within the main asteroid belt located between the orbits of Mars and Jupiter, or are co-orbital with Jupiter (the Jupiter trojans). However, other orbital families exist with significant populations, including the near-Earth objects.What time is the asteroid passing Earth tonight 2019?No compatible source was found for this media. The speedy asteroid, dubbed by NASA 2019 SX5, will fly by on a “Close Approach” trajectory. NASA’s asteroid trackers expect SX5 to appear close to Earth just after midnight on October 11. At its closest, NASA said the space rock will arrive around 12.07am BST on Friday.
