The statement that motion is relative is an important concept in physics. The meaning behind this statement is that the motion of an object is relative to either the frame of reference of the observer, or to another distinct frame of reference.
Asteroids are located in orbits of other planets such as Mars, and Jupiter. There are belts of asteroids around the solar system "behind mars, and next to Jupiter." They orbit the planets and they also have the "Main Asteroid belt which circles around planets 1-4.

Answer:
1830 m /s
Explanation:
The potential energy of the projectile at the surface of planet
- G x 1.46 x 10²³ m / 5 x 10⁶
Kinetic energy at surface
1/2 m v²
Total energy = - G x 1.46 x 10²³ m / 5 x 10⁶ + 1/2 m v²
- 6.67 X 10⁻¹¹ x 1.46 x 10²³ /5 x 10⁶ m + 1/2 m x 2000²
- 1.947 x 10⁶ m + 2m x 10⁶
= .053 x 10⁶ m
Potential energy of projectile at 1000 km height
= - G x 1.46 x 10²³ m / 6 x 10⁶
= - 1.6225 x 10⁶ m J
Total energy
= - 1.6225 x 10⁶ + 1/2 m V ²
Applying conservation of energy in gravitational field at surface and height
- 1.6225 x 10⁶ m + 1/2 m V ² = .053 x 10⁶ m
1/2 V ² = ( .053 + 1.6225 ) x 10⁶
1/2 V² = 1.6755 x 10⁶ m /s
V = 1.83 X 10³ m/s
1830 m /s
