Asteroid 2004 FH Introduction. Asteroid 2004 FH's point of closest approach with the Earth will be over the South Atlantic Ocean. The asteroid known as 2004 FH has an orbit that takes it well within the moon's distance, as this graphic shows. Using a good pair of binoculars, the object will be bright enough to be seen during this close approach from areas of Europe, Asia and most of the Southern Hemisphere. Asteroid 2004 FH on maalähedane asteroid.. 2004. aasta 18. märtsi õhtul möödus Maast väga lähedalt 2004 FH nime kandev asteroid, mis eeldatavasti oli ainult 25 m läbimõõduga. The object, designated 2004 FH, is roughly 30 meters (100 feet) in diameter and will pass just 43,000 km (26,500 miles, or about 3.4 Earth diameters) above the Earth's surface on March 18th at 5:08 PM EST (2:08 PM PST, 22:08 UTC). Large impact features on the Earth are testaments, however, to larger asteroids and comets that actually impacted the Earth in the distant past.

Follow-up astrometry by LINEAR on the next night … The object, dubbed 2004 FH, is probably only about 30 meters (100 feet) in diameter, the size of a small office building. Earth's gravitational pull deflects its path by 15 degrees. The simulation also … 2004FH, as it was designated,was discovered on March 16.3 UT by the NASA-funded LINEAR team, using their 1.0-m f2.15 telescope in New Mexico. Every two years or so, objects about the size of the 2004 FH asteroid pass about as close to the Earth, according to NASA, but they usually pass undetected. On Thursday night, March 18th, a tiny, newly discovered asteroid will make the closest flyby of Earth ever predicted. Short of hitting us that is! An asteroid this size passes this close to Earth about every two years. When: March 18, 2004. Maast möödus see 43 000 kilomeetri kauguselt 18. märtsil kell 22.08 maailmaaja järgi.

A search for meteors potentially associated with the recent spectacular earthgrazing asteroid 2004 FH in the IAU photographic meteor database yields three meteors from the Harvard project, which is probably not enough to support the notion that 2004 FH is one of the larger meteoroids in a stream. A small near-Earth asteroid (NEA), discovered Monday night by the NASA-funded LINEAR asteroid survey, will make the closest approach to Earth ever recorded. Were 2004 FH to have struck the Earth, it would have likely burned up in the atmosphere. Objekt avastati vaid mõni päev varem, 15. märtsil.

This simulation shows the very close encounter of Asteroid 2004 FH with the Earth on 18th March 2004.

On Friday, March 19, 2004, at 11:08 NZDT (March 18 22:08 UT) an approximately 30 metre wide asteroid made the closest, non-impacting approach to Earth so far recorded.
