Unlike any other asteroid known today, Vesta has an iron core surrounded by layers of mantle rock and crust, similar to Earth and Mars, preliminary gravity and density measurements suggest.
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.
"The important thing to consider is that the Earth has a very deep gravity well so anything you can make in situ on the Moon will save an awful lot of energy and therefore money, " he said.
Let me start off by saying one of the nice things about where we physically are right now is that we remove the effects of gravity, so we're able to do experiments that involve the effect of gravity basically on Earth as we look at what happens with the absence of it.

Gravity attracts everything on Earth toward the planet's center.
Gravity attracts all matter on Earth toward the planet's center.
If an object floating through space passes near the line of sight between the earth and a distant star, its gravity should, according to the theory of relativity, bend and focus the light from that star.
As Logan points out, all life on earth has long been steeped in a continuous gravity environment.

It was discovered in 1986 and it takes a convoluted horseshoe path around our planet as it is tossed about by the Earth's and the Moon's gravity.
The gravity assist would allow a safe return to Earth even if the spacecraft's main rocket engine failed, Professor Longuski said.
Laine believes that a Lunar space elevator would be much easier to construct than one on Earth, due to the lack of atmosphere and lower gravity.

If that happened, the Martian gravity would change the spacecraft's trajectory, hurling it toward Venus, where another gravity assist would return the spacecraft back to Earth.
Space is a good place for gerontological study, because of similarities between what happens to a body in zero gravity and what happens naturally over time on Earth.
Here on the Earth's surface we live at the bottom of a gravity well.
These are just some of the momentum stocks that defied the laws of gravity for months, but finally fell back to Earth in recent sessions.
But if it is a rocky world, its gravity would be about 2.4 times that of Earth - there may be life there, but I wouldn't expect to see anything as gracile as our giraffes or whooping cranes.
Changes in the way the light moves comes from the way gravity bends the light as it travels from the quasar towards Earth.
