Believed to be 440–990 metres in dimension, Apollo asteroid 162082 (1998 HL1) passes simply 6.2 million kilometres or barely greater than 16 lunar distances from Earth on the UK night of Friday, 25 October. The physique is predicted to peak at magnitude +12.three, making it a viable goal for 15-cm (6-inch) telescopes and bigger. Click on the graphic to


Believed to be 440–990 metres in dimension, Apollo asteroid 162082 (1998 HL1) passes simply 6.2 million kilometres or barely greater than 16 lunar distances from Earth on the UK night of Friday, 25 October. The physique is predicted to peak at magnitude +12.three, making it a viable goal for 15-cm (6-inch) telescopes and bigger. Click on the graphic to be taken to an interactive HTML5 applet.

Predicted to succeed in a peak magnitude of +12.three on 27 October, this near-Earth asteroid is a viable goal for 6-inch (15-cm) aperture telescopes and bigger for 5 nights because it zips by way of the constellations of Triangulum, Aries and into Cetus at charges of as much as 9 levels/day relative to the background stars.Classed as a Probably Hazardous Asteroid (PHA), 162082 (1998 HL1) is magnitude +13 or brighter because it speeds southeast by way of the constellations of Triangulum, Aries and Cetus between 25 and 29 October. At its closest to Earth on the 25th, 1998 HL1 is travelling at a price of 9 levels/day towards the background stars. The asteroid passes simply zero.four° – lower than a lunar diameter – east of Uranus round 13:30 UT on 27 October, an occasion observable from the antipodes.

The following time it passes nearer to Earth than this apparition is on 26 October 2140 when it zips by our planet at a distance of 6.18 million kilometres, or three.eight million miles.

Found by the Lincoln Close to-Earth Asteroid Analysis (LINEAR) challenge at Socorro, New Mexico on 18 April 1998, 162082 (1998 HL1) is an Apollo-type asteroid that loops the Solar as soon as each 508 days in an eccentric orbit inclined by 20 levels to the ecliptic.
