Below is the list of asteroid close approaches to Earth in 2017.

Timeline of known close approaches less than one lunar distance from Earth in 2017

A list of known near-Earth asteroid close approaches less than 1 lunar distance (0.0025696AU) from Earth in 2017.

For reference, the radius of Earth is approximately 4.26E-05AU or 0.0166 lunar distances.
Geosynchronous satellites have an orbit with semi-major axis length of 0.000282AU or 0.110 lunar distances. In 2017, five known asteroids have traveled nearer than this, 2017 GM, 2017 UJ2, YU95BEF, 2017 EA, and 2017 WE30. P10ELNY and A104Vqx probably have traveled nearer, but knowledge of their orbits is too poor to be sure.

While most asteroids on this list are confirmed, well-observed unconfirmed objects with a 50% or greater chance of passing within 1 LD of the Earth are included as well.

This list does not include any of the 29 objects that collided with earth in 2017, none of which were discovered in advance, but were recorded by sensors designed to detect detonation of nuclear devices (of the 29 objects detected, 6 had an impact energy greater than that of a 1 kiloton device).[1]

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 (size of a person for comparison)Abs Magnitude 29-30Absolute Magnitude 28-29Absolute Magnitude 27-28Absolute Magnitude 26-27Absolute Magnitude 25-26 Absolute Magnitude less than 25 (largest)

Notes

Timeline of close approaches less than one lunar distance from the Moon in 2017

The number of asteroids listed here are significantly less than those of asteroids that approach Earth for several reasons. Asteroids that approach Earth not only move faster, but are brighter and are easier to detect with modern surveys because:

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

Statistics

Virtual impactors

List of asteroids with a Palermo Technical Impact Hazard Scale greater than −6 that are listed on the Sentry Risk Table because they have short observation arcs with poorly constrained orbits and have a chance of impacting Earth in 2017. Given a short observation arc, many different orbits fit the observed data. could have approached Earth around May 2017 or could have been 9 AU from Earth on the way to a close approach with Saturn in 2018. A Palermo rating of −4 indicates an event that is 10,000 times less likely than the background hazard level of Earth impacts, which is defined as the average risk posed by objects of the same size or larger over the years until the date of the potential impact.
