There are estimated to be around one septillion (1,000,000,000,000,000,000,000,000) stars in the universe. Most will have some celestial bodies: space debris if not planets. So which one of these are you interested in?
The closest point in an orbit is called the perigee, for objects orbiting Earth, or periapsis for objects orbiting other celestial bodies.

Some celestial bodies that begin with the letter "A" include asteroids, auroras, and the planet Venus (known as the "Evening Star").
We observe celestial objects from the Earth. Since Earth rotates around the sun we see the celestial objects moving too. So basically due to the rotation of the Earth, celestial objects always seems to move from East to West.Hope that helped Of-course that must have helped, -Hailey xD LOL
Probes are unmanned spacecraft that can be sent to explore celestial bodies within our solar system, typically requiring lower orbital and escape velocities compared to satellites. Satellites are objects that orbit a planet or celestial body, including artificial satellites launched into orbit around Earth. Satellites often require higher orbital and escape velocities due to their continuous or prolonged presence in orbit.
In the context of celestial bodies, "orbit" refers to the path that a celestial body follows around another body due to gravity, such as a planet orbiting a star. On the other hand, "orbital" refers to the specific region in space where an object, like a satellite or spacecraft, moves around a celestial body, following a specific trajectory.
Why the velocities of falling bodies are not proportional to their weights?
In astronomy, an orbital is the path that a celestial body follows as it moves around another body in space, such as a planet orbiting a star. The purpose of an orbital is to maintain the balance of gravitational forces between the two bodies, allowing them to move in a stable and predictable manner. Orbits determine the shape, size, and speed of a celestial body's movement, influencing its position and interactions with other objects in space.

The closest point in an orbit is called the perigee, for objects orbiting Earth, or periapsis for objects orbiting other celestial bodies.
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.
Dates on which celestial bodies were seen
Not necessarily. Two bodies co-orbiting can have different velocities depending on their mass and distance from the central body. The velocities of the bodies would be determined by the balance between gravitational force and centripetal force.
An orbit is the path that a celestial body follows around another body in space, such as a planet orbiting a star. An orbital, on the other hand, refers to the specific path or trajectory of an individual object within that larger orbit, such as a satellite orbiting Earth. In essence, an orbit is the general path, while an orbital is the specific path within that orbit.
Ellipticity is important in the study of celestial bodies and their orbits because it describes the shape of an orbit. The degree of ellipticity can affect the stability and predictability of an orbit, as well as provide insights into the gravitational forces at play. Understanding ellipticity helps scientists analyze and predict the movements of celestial bodies with greater accuracy.
called orbital perturbation. This variation can be caused by the gravitational pull of other celestial bodies, as well as relativistic effects. Scientists study these perturbations to refine our understanding of celestial mechanics and improve the accuracy of our predictions.
