Asteroid 2020 JJ is estimated to be between 9 and 20 feet across, making it a pretty puny little hunk of space junk. The more imminent asteroid is set to be closest to Earth on April 29 and will be traveling at approximately 19,461 mph, according to NASA’s tracking data. The tracking technology is improving, but the tracking technology there are times that we only get a days' warning before an Asteroid is discovered and skims right passed Earth. A newly-discovered asteroid designated 2020 JJ flew past Earth at a very close distance of 0.03 LD / 0.0000896 AU (13 403 km / 8 328 miles) at 12:05 UTC on May 4, 2020. This March 6, 2020, image of the asteroid comes from a single 30-second exposure, remotely taken with Elena, a 17-inch robotic telescope. At its closest in late April, it’ll be about 4 million miles (6.4 million km) away.

A reasonably small 4-8 m asteroid recently flew by Earth, passing close to satellites orbiting in the geostationary ring at a distance of about 42 735 km from Earth… Closest approach of Asteroid 2020 CD3 (Earth's minimoon) to Earth. Apr 20, 2020 11:52 PM EDT ... It’s big – the biggest asteroid due to fly by Earth this year – and will come closest to Earth on April 29, 2020. Asteroid Will Pass “Close” to Earth. Astronomers had no notice of asteroid 2020 JJ’s existence, as it was discovered using the Mt. The top ten closest approaches by an asteroid have all occurred since 2004. This is the 40 th known asteroid to flyby Earth since the start of the year and the second of the month. At the imaging time, (52768) 1998 OR2 was at about 22 million miles (36 million km) from Earth. Lemmon Survey in Arizona right around the time it reached its closest point to us. A decade from now, on April 15, 2029, an asteroid will swing past the Earth, just barely missing everything.The asteroid—nicknamed Apophis—will be as … The asteroid 2020 JJ is the sixth closest approach observed since records began in 1900. The imposing asteroid tracked by NASA’s leading astronomers is expected to cross paths with the Earth’s orbit in 2020. Between January 2015 and December 2100 the closest approach of Asteroid 2020 CD3 (Earth's minimoon) to Earth happens on Tue Apr 26 2044 at a distance of 0.00012101 Astronomical Units, or 18,102 kilometers: NASA keeps an online database of close approaches by asteroids and other ‘near-Earth objects’ going back to 1900 and 2020 JJ comes in as the sixth closest approach ever recorded.
