Below is the list of asteroid close approaches to Earth in 2015.

Timeline of known close approaches less than one lunar distance from Earth in 2015

A list of known near-Earth asteroid close approaches less than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2015.[note 1]

Note this data does not include any of the 43 objects that collided with earth in 2015, none of which were discovered in advance, but were recorded by sensors designed to detect detonation of nuclear devices (of the 43 objects detected, 2 had an impact energy greater than that of a 1 kiloton device).[1]

  Rows highlighted red indicate objects which were not discovered until after closest approach

  Rows highlighted yellow indicate objects discovered less than 24 hours before closest approach

  Rows highlighted green indicate objects discovered more than one week before closest approach

  Rows highlighted turquoise indicate objects discovered more than 7 weeks before closest approach

  Rows highlighted blue indicate objects discovered more than one year before closest approach (i.e.
objects successfully cataloged on a previous orbit, rather than being detected during final approach)

Warning Times by Size

This sub-section visualises the warning times of the close approaches listed in the above table, depending on the size of the asteroid. The sizes of the charts show the relative sizes of the asteroids to scale. For comparison, the approximate size of a person is also shown. This is based the absolute magnitude of each asteroid, an approximate measure of size based on brightness.

Abs Magnitude 30 and greater

  • 2015 VO142 (~6 meters in diameter) passed 1.02 lunar distances (393,000 km) (0.85 lunar distances from the Moon) (327,000 km) on 24 November 2015
  • Risk-listed asteroid 2007 VE191 (~60 meters in diameter) was not observed when it probably passed roughly 0.5 AU (75,000,000 km; 46,000,000 mi) from Earth on 27 November 2015.
  • 2015 YB initially calculated to make a close approach to Earth on 19 December 2015 turned out to be a much further away inner main-belt asteroid. On 31 December 2015 the asteroid received the designation 2015 YU9.

Timeline of close approaches less than one Lunar distance from the Moon in 2015

The number of asteroids listed here are significantly less than those of asteroids approaching Earth for several reasons:

  • Asteroids approaching Earth not only move faster, but are brighter and are easier to detect with modern surveys due to these factors
  • Asteroids approaching closer to Earth are higher priority to confirm, and only confirmed asteroids are listed with a lunocentric approach distance
  • Those which make close approaches to the Moon are frequently lost in its glare, making them harder to confirm, and are more easily discovered during the new Moon, when the Moon is too close to the Sun for any asteroids to be detected while they are near to the Moon anyway.

These factors combined severely limit the amount of Moon-approaching asteroids, to a level many times lower than the detected asteroids to pass just as close to Earth instead.
