Does gravitational force maintain the shape of the solar system? What is the mass of the Sun? Does Earth have a gravitational force which affects other stars? What are the effects of distance and mass on the gravitational pull of the planets?
Answer to: What would the Sun's gravitational force on the Earth be if the Earth had twice its present mass? Would the Earth's acceleration change?...
Jupiter, Earth, and Sun After Newton's triumph in explaining Kepler's laws, the next natural question was how the mutual gravitational forces between the planets affected their motion. Vast efforts were spent understanding how the exact solution to the two-body problem was possible: the key role...
If the distance between sun and earth is increased by 3 times, then attraction between two will ARemains constant BDecrease by 63% CIncrease by 63% DDecreases 89%Submit If the distance between the sun and the earth is increased by three times, then the gravitational force between two will...
To calculate the gravitational force between the Sun and the Earth, we can use Newton's law of universal gravitation, which states: F=Gm1m2r2 Where:- F is the gravitational force,- G is the gravitational constant, approximately 6.674×10−11N m2/kg2,- m1 is the mass of the first obje...
Optimal control of a spacecraft orbiting the Moon in a Sun-synchronous orbit that provides consistent illuminati on and efficient imaging for mapping is investigated in this paper. The perturbations due to the gravitational force from the Earth, Sun and the non-spherical gravity field of the Moon...

The gravitational force exerted by the Sun on the Earth holds the Earth in an orbit around the Sun. Let us assume that the orbit is perfectly circular. The work done by this gravitational force during a short time interval in which the Earth moves through a displacement in its orb...
Here's a list of some interesting facts about stars.The sun is the closest star to the earth.The sun is about 150 million kilometres away.Our sun, like most other stars, gives off power and light by nuclear fusion(核聚变), which happens exactly where it's the hottest. The sun is abo...
