It is not circling the Earth but orbits a point in the Sun-Earth system called the second Lagrange point.
To the sun, the Earth is a tiny speck: its diameter is less than 0.01% of the Earth-sun distance.
There are probably many more comets than near-Earth asteroids, but Nasa points out they spend almost all of their lifetimes at great distances from the Sun and Earth, so that they contribute only about 10% to the census of larger objects that have struck the Earth.
At this point in space, the gravity of the Earth and the Sun act in such a way that the telescope will be stationary relative to the Earth and Sun.
These momentarily warmer periods coincided with times when orbital positions of Jupiter and Saturn were relatively close to the Sun and Earth.
FORBES: Global Warming? No, Natural, Predictable Climate Change
The probe's five-year mission is the cornerstone of a NASA science program called Living with a Star, which aims to help scientists better understand aspects of the sun-Earth system that affect our lives and society.
The Italian physicist concluded in the 1600s that the sun did not, in fact, travel around the earth, but that the earth orbited the sun, bucking Catholic logic that the earth was the center of the universe.
During an eclipse scientist are able to measure the effect of the sun on the Earth's atmosphere and observe the violent magnetic storms in outer atmosphere of the sun - the corona.
The shift is as transformational as the shift from the medieval view that the sun revolves around the earth to the view that earth and the other planets revolve around the sun.
FORBES: Toward The Tipping Point In Leadership And Management
The shift in management paradigm is as transformational as the shift from the medieval view that the sun revolves around the earth to the view that earth and the other planets revolve around the sun.
FORBES: The New Management Paradigm & John Mackey's Whole Foods
Early of the Lawrence Livermore National Laboratory, California, proposed siting a vast, 2000 km-wide glass deflecting panel at the "inner Lagrange point" between the Earth and the sun, the latter diverting the sun's rays away from the Earth's atmosphere.
CNN: The shield of Ra: Could solar reflection save the planet?
Under a blazing sun, the earth was baked dry, and the GM wheat, a pale green, twitched and fluttered in the breeze.
In February last year a large solar flare erupted, disrupting flights over Pacific, but the bulk of the material emitted by the Sun passed by Earth.
This is just one of several hundred rocks, varying in size from a few metres to a few kilometres across, whose orbits around the sun cross the Earth's.
AU, is the distance from the sun to the earth, so the position of the dust coincides with that of the rocky planets of the earth's solar system.
The researchers used data from the global network of solar monitoring telescopes (Gong) as well as the Soho satellite positioned in a stable orbit 1.6 million km (a million miles) closer to the Sun than the Earth.
Green aficionados are familiar with the statistic that the sun bathes the Earth in trillions of barrels of energy (in oil equivalent terms), and less familiar with the fact that total known hydrocarbon resources are also countable in the trillions of barrels (from the oil-sands and ultra-deep-water sub-salt fields, to methane hydrates and coal, not to mention shale gas).
It is currently 13.5 billion kilometres (8.4 billion miles) from the Sun, or 90 times the distance separating the Earth from the Sun.

Since Kepler 62 is a cooler star than our sun, planets can orbit closer to it than the Earth can to our sun before overheating.
Now only visible with the largest ground-based telescopes or from space, 1999 RQ36 currently lies about one earth-sun distance away.
FORBES: New Observations Signal NASA Mission's Target Asteroid Is Sample-Friendly Rubble Pile
The NASA-funded researcher has been studying elusive magnetic portals connecting the Earth and Sun, and now he's figured out how to find them.
This same Nobel prize winner also wants to paint roads and roofs white to reflect sun heat away from earth to reduce global warming.
FORBES: NRC: Vermont Yankee Nuclear Power Plant 'Good to Go' for 20 More Years
These craft will study the interaction between the solar wind (the breeze of electrically charged particles emitted by the sun) and the earth's magnetic field.
"You can maintain a good geometry - the Earth and Sun are always in the same direction, " says Martin Hechler who has helped to design the mission path out to L2.
This was actually launched in 1998, but it followed a complicated fuel-saving orbit that sent it around the sun and back to Earth, to be slung towards Mars at the same time as the other missions took off.
ECONOMIST: The current crop of Mars missions has got off to a bad start
Similarly, one camp maintains that temperatures are rising dramatically with unspeakable portents, while the other thinks what has happened is entirely a result of undefined internal oscillations in the earth-sun climate system, and that there is virtually no human component to climate change.
FORBES: Global Warming: Hotheads, Flatliners and Lukewarmers, Part One
Two thousand years hence, Sherwood says hypothesized collections of Asteroidal materials congregating at the Earth-Sun L4 and L5 gravitational equilibrium points would make for building materials to construct a large rotating pancake disk capable of housing thousands of people in the comfort of a free-breathing atmosphere and some form of artificial gravity.
FORBES: Space Architecture And View Condos In Low Earth Orbit
Solar energy can, of course, be gathered on Earth, but only about half of the sun's radiation ever makes it to the Earth's surface--the rest is either absorbed by the atmosphere or reflected back by clouds.
That is only a twentieth of the mean distance between the Earth and the Sun.
Its distance from this star is only 5% of that between the Earth and the sun.
