A newly discovered Apollo-class asteroid 2017 BX will flyby Earth at 0.68 LD (261 120 km / 162 252 miles) from the surface of our planet on January 25, 2017. Its estimated size is between 4 and 14 m (13 and 46 feet).
At the time of its closest approach to Earth - 04:45 UTC on January 25 - asteroid 2017 BX will flyby at 0.68 LD (261 120 km / 162 252 miles) from the surface of Earth with an estimated velocity of 7.44 km/s.
2017 BX was first observed at Pan-STARRS 1, Haleakala on January 20, 2017.
The next time this object comes close to our planet will be on January 12, 2070. Its nominal distance at the time of closest approach will be 37.9 LD (14553603 km / 9043190 miles).
As of January 17, 2017, there are 15 564 known near-Earth objects. On January 1, 2000, this number was only 935. Ten years before that, on January 1, 1990, we knew only for 180 near-Earth objects.
The following chart shows the current total number of known near-Earth asteroids (as of January 21, 2017) grouped according to their estimated sizes. The first size bin represents NEAs smaller than ~30 m (98 feet) in diameter. The last bin represents NEAs with diameters larger than ~1km (0.62 miles).
