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.
What else can I help you with?
What space objects are made of chunks of rock?
Asteroids, meteoroids, and comets are space objects that are made of chunks of rock. Asteroids are rocky bodies that orbit the Sun within the asteroid belt, meteoroids are smaller rocky fragments that travel through space, and comets are a mixture of rock, dust, ice, and frozen gases.
Why is earth not effected?
Earth is not affected by the gravitational pull of other objects in space because it is in a stable orbit around the sun. The gravitational force between the Earth and the sun is much stronger than the gravitational pull from other objects in space. Additionally, Earth's distance from these objects and its velocity allow it to maintain its orbit without being significantly affected.
What force keeps the Earth in its orbit and stops it flying off into space?
The force that keeps the Earth in its orbit and prevents it from flying off into space is gravity. Gravity is generated by the mass of the Earth and pulls objects toward its center, creating the centripetal force that maintains the Earth's orbit around the Sun.
What is the largest telescope to be put into orbit?
The largest telescope put into orbit is the James Webb Space Telescope (JWST). Scheduled to launch in late 2021, the JWST will have a mirror diameter of 6.5 meters, significantly larger than the Hubble Space Telescope.
What is space pollution?
Space pollution is the collection of defunct objects in the space around Earth. It includes everything that can be considered debris, from old satellites, spent rocket stages and rock fragments from erosion and collision.
What makes the moon and a planet alike?
Both moons and planets are objects in space that orbit a larger body.
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.
How do objects in space move around other objects in space?
Objects in space move around other objects due to gravitational forces. These forces cause objects to orbit around a more massive body, like planets around a star, based on their mass and distance. The path an object follows is known as an orbit and is determined by a balance between the object's velocity and the gravitational pull of the larger body.
How does the concept of gravitize affect the movement of objects in space?
The concept of gravitize, or gravity, affects the movement of objects in space by exerting a force that pulls objects towards each other. This force influences the trajectory and speed of objects in space, causing them to orbit around larger bodies like planets or stars.
What is the definition of gravitational strength and how does it impact the motion of objects in space?
Gravitational strength refers to the force of attraction between two objects due to their mass. In space, this force influences the motion of objects by causing them to orbit around larger objects, such as planets or stars. The strength of gravity determines the speed and trajectory of these objects as they move through 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.
When two objects of unequal mass orbit where is the center of the mass?
The center of mass is closer to the larger object, specifically inside the larger object since mass affects the center of mass. As a result, the larger object will exert a greater gravitational force on the smaller object, causing both objects to orbit around the center of mass.
Why do the larger outer planets have more satellites than the smaller planets?
This is because the larger planets have more of a gravitational pull. The higher attraction you have to other objects the more likely you are to have them around you. Some believe earth only has a moon because it collided with us from space.
What technique is illustrated by making objects in the foreground larger that objects in the backround?
This technique is called "relative size" and it is used in art to create the illusion of depth and distance in a two-dimensional space. By making objects in the foreground larger, they appear closer to the viewer, while objects in the background appear smaller and further away.
Why do smaller planets always orbit larger planets?
Moons orbit planets, though they could sometimes be thought of as small planets. Objects are kept in orbit by the force of gravity. If something crashes into a planet and pieces of rock fly everywhere, they will be pulled together by the gravity of the planet and will start to orbit it. If an asteroid or large rock in space gets too near a planet, the planet's gravity will sometimes 'capture' it and keep the asteroid in orbit. ______________ Our moon orbits the earth in an elliptical orbit (almost all orbits in the solar system are elliptical). The interesting thing that may provide a satisfying answer to your interesting question is that objects really orbit each other; it is not a matter of one of the objects doing the orbiting all by itself. If you and a friend hold the ends of a rope and then begin to move in circles, you will find that you each will move in a circle, not just one of you. The one with the more mass will move in a smaller circle, but if you are identical, your movements will be the same. The earth and the moon each have mass, so each pulls on the other. Earth and moon orbit around the center of gravity of the earth/moon system. This center of gravity happens to be within the body of the earth, but it is not at earth's center. Two objects of the same mass will swirl around each other with their center of gravity half way between them. There are even systems of double stars that are in orbit around each other in this way.
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.
