Gravitational lensing.
Asteroid belts are not individual celestial objects themselves, but rather regions in space between planets that contain numerous small rocky bodies called asteroids. These belts are typically located in the inner regions of the solar system, such as between Mars and Jupiter.
Astronomers use celestial spheres and mathematical equations to approximate the distances between the star and other celestial objects.
The space rock is the celestial space object that a meteoroid comes from.
Peculiar velocities are the individual speeds at which celestial objects move within a larger system, like a galaxy or galaxy cluster. These velocities can cause objects to deviate from the overall motion of the system, leading to variations in their trajectories and positions. This can impact the interactions between celestial objects and influence their overall motion within the system.
A specific location in space can be identified by its coordinates, which can include its distance from a reference point and its direction relative to other objects. Astronomers often use celestial coordinates such as right ascension and declination to pinpoint the location of celestial objects in the sky.
You could call it interstellar or interplanetary space, depending on the context of the objects involved.
Gravitational force is the attraction between two objects with mass, like celestial bodies such as planets and stars. The force of gravity depends on the mass of the objects and the distance between them. The larger the mass of an object, the stronger its gravitational pull. The closer two objects are, the stronger the gravitational force between them. This force keeps celestial bodies in orbit around each other and governs their movements in space.
There are two. There is Special relativity, the one that says you can't go faster than the speed of light. Then there is General relativity, the one that describes gravity as bending space rather than as a Newtonian attraction between objects.
Declination, which measures the angle between the direction of a celestial object and the celestial equator, ranges from +90 degrees to -90 degrees. A declination of +90 degrees indicates the North Celestial Pole, while -90 degrees indicates the South Celestial Pole. Values between these extremes represent the position of celestial objects in the sky relative to the celestial equator.
The term you are looking for is "asteroid belt." It is a region in the solar system that is mostly located between the orbits of Mars and Jupiter and is home to numerous small celestial objects called asteroids.
