Designated 2004 JG6, this asteroid was found in the course of LONEOS (the Lowell Observatory Near-Earth Object Search) on the evening of May 10 by observer Brian Skiff.
In addition, 2004 JG6 goes around the Sun in just six months, making it the asteroid with the shortest known orbital period.

Such asteroids are very difficult to detect because their position in relation to the Sun and the Earth means they rarely appear in the night sky.
The asteroid, designated 2004 JG6, was spotted earlier in May by Brian Skiff, part of the Lowell Observatory Near-Earth Object Search (LONEOS), in Flagstaff Arizona, US, reports newscientist.com.

The asteroid, designated 2004 JG6, was spotted earlier in May by Brian Skiff, part of the Lowell Observatory Near-Earth Object Search (LONEOS), in Flagstaff Arizona, US.
JG6 flies closer to the Sun than Mercury for part of its orbit, but there are several objects that make even closer approaches, says Brian Marsden, director of the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts.
While JG6 and the asteroid discovered in 2003 fly entirely within the Earth's orbit, there are thought to be some asteroids orbiting entirely within the path of Mercury.

Among the projects they are currently working on are: the technological requirements of nuclear propulsion and missions it might lead to, such as a spacecraft to orbit Pluto; the extreme difficulty of building an antimatter engine; the best routes for interstellar spacecraft to take between stars; the possibility of nudging dangerous asteroids.
As shown in this diagram, JG6 crosses the orbits of Venus and Mercury, passing less than 30 million miles from the Sun every six months.
From present estimates, 2004 JG6 is probably between 500 meters and 1 km in diameter.

 apohele
Now, however, there are two known apoheles: 2003 CP20 and 2004 JG6.
In addition, the 40-m-wide object 1998 DK36, discovered by Tholen and Robert Whiteley in February 1998, may have been an apohele but it was observed on only two consecutive days and subsequently lost due to failure of the observing instrument.
2004 JG6 is particularly interesting in that its orbital period is less than that of Venus, making it the second-closest known object to the Sun, second only to Mercury.

Thus, although it approached the Earth closer than did asteroid 2004 FH on March 18, it is only about 1/200 the mass (most probable mass is about 150 tons), and would have posed only a very minor local hazard had it actually hit the Earth.
The closest encounter in March was made by asteroid 2004 FU162, which passed within 12,900 km of the centre of the Earth at 1536 UT. However, this fact was not realised until much later.
Although this is not the nearest miss distance recorded for an asteroid(one was filmed passing through the Earth's atmosphere before heading back to space three decades ago), it is the closest approach of an asteroid that had been observed before the approach.

They have not only their perihelion at less than one AU (within Earth's orbit), but also their aphelion; that is, their entire orbit is within Earth's.
As of July 2004 there are only two confirmed Apoheles: 2003 CP and 2004 JG An earlier object, 1998 DK, has not been seen since February 24 1998 and its discoverer David J. Tholen acknowledges that it is currently lost.

 Universe Today - Closest Asteroid to the Sun Found
Summary - (May 21, 2004) While searching for near Earth-asteroids, astronomers at Lowell Observatory found an object which orbits closer to the Sun than any other asteroid.
Designated 2004 JG6, the asteroid is probably between 500 - 1,000 metres in diameter (1,600 - 3,200 feet) and takes about six months to go around the Sun.
Objects like this, which travel within Earth's orbit are called Apoheles, and they're very difficult to discover because they spend so much time near the Sun, invisible to telescopes in the daytime sky.

Lowell research assistant Brian Skiff observed the object known as "2004 JG6" on May 10, in the early evening during a brief window of time when objects close to the sun are visible.
Skiff said 2004 JG6 has an elliptical orbit and scoots past the sun at a distance of 27 million miles -- inside Mercury's orbit -- at its closest point.
It then arches out beyond Venus until it is 90 million miles away, only 3 million miles inside Earth's orbit.

Astronomers at Lowell Observatory in Arizona discovered the asteroid, designated 2004 JG6, on May 10, and immediately noticed its unusual orbit.
The asteroid's orbit lies entirely within the Earth's, coming within 5.6 million kilometers from the orbit of the Earth at aphelion and just 3.2 million kilometers from the orbit of Mercury at perihelion.
2004 JG6 is only the second asteroid discovered to date, after 2003 CP20 last year, that is always closer to the Sun than the Earth.

- sol 131-133, May 20, 2004 Spirit continued its trek to the "Columbia Hills" over the past four sols, but took an unplanned break on Sols 131 and 132 due to a software fault on sol 131.
That fault left rover planners with some uncertainty about Spirit's final position and attitude, so Sol 132 was spent re-establishing that knowledge with panoramic, navigation and hazard avoidance camera imaging of the rover's surroundings.

The team estimates that the rock, designated 2004 JG, has a diameter between 500 meters and 1 kilometer.
Residing between the orbits of Venus and Mercury on an elongated path, 2004 JG6 is only the second known asteroid with an orbit entirely within Earth's, notes Ted Bowell, who collaborated with Skiff.
Most asteroids lie between the orbits of Jupiter and Mars, and calculations by William Bottke of the Southwest Research Institute in Boulder, Colo., suggest that only 2 percent of near-Earth asteroids come as close to Earth as 2004 JG does.

Researchers from the University of Toronto and the Geological Survey of Canada have determined that a meteorite collision caused part of the Earth's crust to flip inside out billions of years ago and left a dusting of a rare metal scattered on the top of the crater.
The study, published in the June 3, 2004, issue of Nature, examines the devastating effects of meteorite impacts on the Earth's evolution.
