Near Earth Objects

Near-Earth Objects (NEOs) are comets and asteroids that have been nudged by the gravitational attraction of nearby planets into orbits that allow them to enter the Earth's neighborhood. Composed mostly of water ice with embedded dust particles, comets originally formed in the cold outer planetary system while most of the rocky asteroids formed in the warmer inner solar system between the orbits of Mars and Jupiter.

The scientific interest in comets and asteroids is due largely to their status as the relatively unchanged remnant debris from the solar system formation process some 4.6 billion years ago. The giant outer planets (Jupiter, Saturn, Uranus, and Neptune) formed from an agglomeration of billions of comets and the left over bits and pieces from this formation process are the comets we see today. Likewise, today's asteroids are the bits and pieces left over from the initial agglomeration of the inner planets that include Mercury, Venus, Earth, and Mars

The vast majority of NEOs are asteroids, referred to as Near-Earth Asteroids (NEAs). NEAs are divided into groups (Aten, Apollo, Amor) according to their perihelion distance (q), aphelion distance (Q) and their semi-major axes (a). See table
Group Description Definition
NECs Near-Earth Comets q<1.3 AU, P<200 years
NEAs Near-Earth Asteroids q<1.3 AU
Atiras NEAs whose orbits are contained entirely with the orbit of the Earth
(named after asteroid 163693 Atira).
a<1.0 AU, Q<0.983 AU
Atens Earth-crossing NEAs with semi-major axes smaller than Earth's
(named after asteroid 2062 Aten).
a<1.0 AU, Q>0.983 AU
Apollos Earth-crossing NEAs with semi-major axes larger than Earth's
(named after asteroid 1862 Apollo).
a>1.0 AU, q<1.017 AU
Amors Earth-approaching NEAs with orbits exterior to Earth's but interior to Mars'
(named after asteroid 1221 Amor).
a>1.0 AU, 1.017<q<1.3 AU
PHAs Potentially Hazardous Asteriods: NEAs whose Minimum Orbit Intersection
Distance (MOID) with the Earth is 0.05 AU or less and whose absolute
magnitude (H) is 22.0 or brighter.
MOID<=0.05 AU, H<=22.0

NEO - RECENT CLOSE APPROACHES TO EARTH

Near Earth Objects - Our solar system is teeming with asteroids and comets, some of which periodically pass close to Earth. These space rocks, called near-Earth objects, provide good opportunities for study and can also be potentially dangerous to Earth. Ask the dinosaurs !!!

April 28th 2020
ASTEROID NEAR MISS:
A newly-discovered asteroid designated 2020 HS7 will flyby Earth at a very close distance of 0.11 LD / 0.00029 AU (43 383 km / 26 957 miles) at 18:51 UTC on April 28, 2020.

September 1st 2018
ASTEROID NEAR MISS:
Asteroid named 'Florence' and is about 2.7 miles in length NASA has warned that the largest Earth-bound asteroid ever seen by NASA Florence will fly by at a relatively safe distance of 4.4 million miles away, around 18 times the distance between the Earth and the moon, but still close enough to be classed as a near-Earth object. It will be visible in small telescopes for several nights as it moves through the constellations Piscis Austrinus, Capricornus, Aquarius and Delphinus.

October 12th 2017
ASTEROID NEAR MISS:
2012 TC4 The large space rock, named 2012 TC4, was first spotted five years ago by the Pan-STARRS telescope at the Haleakala Observatory, in Hawaii, before disappearing as it orbits the sun. It then reemerged in July on a trajectory well inside our lunar orbit. Scientists said the asteroid swung by Earth about 6:42am BST, 42,000 kilometers) above Antarctica at 0542 GMT Thursday. That's about 11 percent the distance between Earth and the moon, and just beyond the orbit of geostationary satellites..

September 1st 2017
ASTEROID NEAR MISS:
At 1206 GMT, the roughly 2.7-mile-wide (4.4 kilometers) asteroid 3122 Florence came within a mere 4.4 million miles (7 million km) of Earth — just 18 times the distance from our planet to the moon.

April 19th 2017
ASTEROID NEAR MISS:
According to NASA, the asteroid 2014 JO25 will come within 4.6 lunar distances, This will be the closest of an asteroid of this size since a September 2004, with an estimated diameter of 0.65 km, larger than the Rock of Gibraltar.

February 2nd 2017
ASTEROID NEAR MISS:
A newly discovered asteroid 2017 BS32 will flyby Earth on February 2, 2017 at a distance of 0.41 LD from the surface. This near-Earth object belongs to Aten group of asteroids. 2017 BS32 was discovered on January 30 by Pan-STARRS 1, Haleakala. Its estimated size is between 11 and 25 m (36 to 82 feet). It will flyby Earth at 20:27 UTC on February 2 at a distance of 0.41 LD (161 280 km / 100 214 miles) from the surface at a speed (relative to Earth) of 11.56 km/s.

This is the fourth know near-Earth asteroid to pass very close to Earth (below 1 LD) since January 8, 2017

January 26th 2015
ASTEROID NEAR MISS:
The asteroid 2004 BL86 will fly by Earth on Jan. 26, passing at a range of about 745,000 miles (1.2 million kilometers), about three times the distance between the Earth and the moon. It will be the asteroid's closest approach to Earth for the next 200 years, according to NASA scientists. Asteroid 2004 BL86 is nearly 1,800 feet (549 meters) in diameter, but there is no risk of it hitting the Earth when it zips by. The next asteroid of similar size to come near Earth will be the asteroid 1999 AN10, which will make its closest approach in 2027, according to the NASA statement

February 18th 2014
ASTEROID NEAR MISS:
Asteroid 2000 EM26. A "potentially hazardous" asteroid the size of three football fields will come uncomfortably close to Earth early on Tuesday. The space rock, known as 2000 EM26, poses no threat and will pass the Earth at just under nine times the distance to the moon. But it is defined as a potentially hazardous near-Earth object (NEO) large enough to cause significant damage in the event of an impact. Scientists estimate the asteroid, travelling at 27,000mph, is 270 metres (885ft) wide. At its closest approach at 2am UK time, the rock will be 2.1m miles from Earth, or 8.8 lunar distances.

February 15th 2013
ASTEROID NEAR MISS:
Asteroid 2012 DA14 will be closest to Earth on February 15, 2013 at about 19:24 GMT (2:24 p.m. EST or 11:24 a.m. PST), when it will be at a distance of about 27,700 kilometers (17,200 miles) above the Earth's surface. This is so close that the asteroid will actually pass inside the ring of geosynchronous satellites, which is located about 35,800 kilometers (22,200 miles) above the equator, but still well above the vast majority of satellites, including the International Space Station. At its closest, the asteroid will be only about 1/13th of the distance to the Moon. The asteroid will fly by our planet quite rapidly, at a speed of about 7.8 kilometers/second (17,400 miles/hour) in a south-to-north direction with respect to the Earth

15/2/2013 03:20 GMT In a seperate incident a meteor crashing in Russia's Ural mountains has injured at least 950 people, as the shockwave blew out windows and rocked buildings. Many videos have appeared on the internet
January 27th 2012
ASTEROID NEAR MISS:
2012 BX34 is a small Aten asteroid that made a close flyby of the Earth on 27 January 2012. The asteroid passed within 0.0004371 AU (65,390 km; 40,630 mi) of Earth during its closest approach at 15:25 GMT, conducting one of the closest asteroid passes on record. 2012 BX34 measures around 8 meters (26 ft) across; if it had impacted in 2012, it would have been too small to pass through Earth's atmosphere intact.
November 8th 2011
ASTEROID NEAR MISS:
Near-Earth asteroid 2005 YU55 passed within 0.85 lunar distances from the Earth. This was the closest an asteroid has been to Earth in 200 years, according to Nasa. It is also the largest space rock fly-by Earth has seen since 1976; the next visit by a large asteroid will be 2028. The aircraft-carrier-sized asteroid was darkly coloured in visible wavelengths and nearly spherical, lazily spinning about once every 20 hours as it raced through our neighbourhood of the Solar System.
January 13 2010
ASTEROID NEAR MISS:
at 12:46 pm Greenwich time Asteroid 2010 AL30, will make a close approach to the Earth's surface to within 76,000 miles, about 10-15 meters across.
Novemeber 6th 2009
ASTEROID NEAR MISS:
at 2132 UT, asteroid 2009 VA barely missed Earth when it flew just 14,000 km above the planet's surface. That's well inside the "Clarke Belt" of geosynchronous satellites. If it had hit, the 6 metre wide space rock would have disintegrated in the atmosphere as a spectacular fireball, causing no significant damage to the ground. 2009 VA was discovered just 15 hours before closest approach by astronomers working at the Catalina Sky Survey.
