If you take a mechanical model of the solar system, grab the earth; then the sun will orbit it and the planets will "adopt" a elliptical orbit. However; observations of extra-solar system planets show that stars are stationary, except for a slight "wobble" as they ACTUALLY orbit their COMMON center of gravity which is VIRTUALLY near the star given it's having the bulk of the mass, thereby giving the impression of it being PERFECTLY stationary relative to a satellite. But; of the underlying physical mechanism whereby a larger object remains central there must be a "stay put" factor to it's superior "spinning power" even as a spinning top has the tendency to "stay put" whilst it is doing so.
Whether this phenomena is describable in physics I don't know.
Incidentally, the physics of the gyration of a spinning top, and also the similar precision of the equinoxes on earth is UNKNOWN and a great mystery in science.

How many natural and artificial satellites does Earth have?
Earth has one natural satellite (the moon). There are also several stray rocks in odd orbits but none of these is considered significant or long-term. The United States Space Surveillance Network is tracking more than 8000 man-made objects in orbit that are 10 cm in diameter or larger. About 560 of these are artificial satellites (i.e. constructed objects intentionally placed in orbit to perform some function), the rest are debris being tracked to prevent its reentry being mistaken for an incoming missile.
What produces lunar soil?
impacts from space objects
Why do all celestial objects in space not lie on the celestial sphere?
because the objects exist at different distances from earth.
The earth undergoes three main motions of space what are these?
The three major motions that the Earth undergos in space are Revolution(Orbit), Rotation, and Precession
What three changes in the earth's movement in space might result in long-term climatic changes?
The shape of the orbit, the distance of the orbit from the Sun, and the angle of the rotational axis.
What makes the moon and a planet alike?
Both moons and planets are objects in space that orbit a larger body.
How does a space shuttle accelerate in space?
By reducing its velocity and dropping to a lower orbit. Objects in low orbit travel around the earth faster due to the orbit's smaller circumference. Conversely, it slows down by increasing its velocity and ascending to a higher orbit with a greater circumference.
In space does the smaller object orbit around the larger object or does the larger object around the smaller object?
Both objects orbit around their common center of mass. For both the sun-earth case, and the moon-earth case, the large body is so much more massive than the small one that their common center of mass is inside the larger one. So in both cases, it would look like the smaller one is orbiting the larger one. But if you had two 12-pound bowling balls doing a gravitational orbit on a lazy Saturday afternoon outside the window of the Space Shuttle, you'd see both of them circling the point half-way between them.
What keeps planets in orbit and why?
there isn't any resistance in space so if something is moving in space, it won't stop until some kind of resistance occurs. the gravitational force and the associated attraction keeps the asteroids moving in space.
What is a rock in space without an orbit?
Impossible. All objects in space have an "orbit" - it just means the path that they're traviling.
What are the large objects in space that orbit a star such as the sun?
The answer is planets.
What did he do with the gravity?
Gravity is the resulting force created, as infinitely smaller and smaller masses orbit larger masses in space, which allows matter to become compacted into smaller and more dense proximity, and at the same time, creating a relative void in space, which causes the less massive of two bodies in space, to continually fall toward the more massive body in space.
What is the name of the group of objects of orbit the sun between mars?
space junk
What are all objects in space constantly doing?
Objects in space are always Floating and/or orbiting a larger object because of the lack of gravity in space.
Where does a space shuttle go?
hooks up to the space station they just fly into space, where they are put into orbit around earth. when in orbit, they can hook up to flying objects to do repairs or building.
When and object mover around objects in space ina regular path it is called w ha t?
an orbit
How is visual acuity used in architecture?
Perception affects visual acuity and the perceived size of objects. Perception can make a space look larger or smaller than it actually is.
