How does the sun's gravity affect the planets?
Yes. The sun is attracted by the gravity of the planets just as the planets are attracted by the sun. Since the sun is more massive it does not move as much, bu the gravity of the orbiting planets does cause it to "wobble."
What phenomena are gravity responsible force?
Gravity is responsible for keeping all sorts of things in their orbits - planets around the Sun, suns around the Milky Way, moons around their planets, among others.It is also responsible for keeping things together - Earth, for example, would quickly fall apart without gravity.
What is the value of the acceleration of gravity?
1. what value is assigned to the acceleration due to gravity on earth? The acceleration of gravity on earth is 9.8 meters per second per second. 9.8m/s2 2. what is the initial velocity of an object that is dropped? That would be Vi=0.
Does circular motion occurs only occures only on earth?
No, there are circular movements just about anywhere: planets, moons and stars rotating, planets orbiting their stars, moons orbiting their planets, and stars orbiting their galaxies, often in orbits that are fairly circular, etc.
What does the earth's magnetic field not affect?
other planets
How many stages are in The condensation theory?
There are six different stages in the condensation theory. These include the formation of a nebula cloud, the formation of a sun, the formation of planetesimals, the expulsion of gases from the forming sun, the growth of the planetesimals, and the formation of larger planets from planetesimals.
What collided to form planets with13 letters?
Planetesimals.
How many planets involve around your sun?
8 planets and explanet pluto.
What is the term used to describe an object that is much smaller than a planet and which condensed from a cloud of interstellar gas and dust?
Scientists believe that the solar system is about 4.5 billion years old, and that it began as a cloud of interstellar gas and dust. This cloud of matter then condensed and fragmented into tiny ( compared to planets ) objects called planetesimals. These planetesimals then came together due to gravity to from the planets we know now. It is thought that many asteroids are planetesimals that never came together.
Does the size of a planet has any impact on the eccentricity of a planets orbit?
No but the sizes of OTHER planets and planetesimals can and do.
How the rocky inner planets were formed?
By "accretion" of "planetesimals" from the "protoplanetary disk".
What effect do collisions among planetesimals of greatly varying size have on the formation of planets?
The small ones get to be "swallowed up" by the bigger ones, because of gravity. Eventually, the planetesimals can develop into planets by this process, which called "accretion".
Will the planets colide?
No, the solar system planets are all in stable orbits. That may not be the case for the asteroids, comets, and distant planetesimals.
What is the process by which planets and other satellites are formed from planetary particles of gas and dust that collide and stick together?
Inertia
Why do the planets do not collide?
They are in their own orbit
Do planets get bigger when they collide?
Yes and No
What are the small bodies made of rock and ice that became the building blocks for planets called?
planetesimals
