2024年11月8日 · What Is an Orbit? The Short Answer: An orbit is a regular, repeating path that one object in space takes around another one. An object in an orbit is called a satellite. A satellite can be natural, like Earth or the Moon. Since the Earth orbits the Sun, you’re actually in orbit right now! Many planets, like Earth, have moons that orbit them.

Orbit - Wikipedia
In celestial mechanics, an orbit (also known as orbital revolution) is the curved trajectory of an object [1] such as the trajectory of a planet around a star, or of a natural satellite around a planet, or of an artificial satellite around an object or position in space such as a planet, moon, asteroid, or Lagrange point.
Chapter 5: Planetary Orbits - NASA Science
Upon completion of this chapter you will be able to describe in general terms the characteristics of various types of planetary orbits. You will be able to describe the general concepts and advantages of geosynchronous orbits, polar orbits, walking orbits, Sun-synchronous orbits, and some requirements for achieving them.

2022年5月3日 · An orbit is the route that one space object repeatedly takes around another. Comets — such as Neowise C/2020 F3, seen here — travel around the sun in very elliptical orbits. Even in ancient times, stargazers knew that planets differed from stars.

2020年3月30日 · What is an orbit? An orbit is the curved path that an object in space (such as a star, planet, moon, asteroid or spacecraft) takes around another object due to gravity. Gravity causes objects in space that have mass to be attracted to other nearby objects.
What Is An Orbit & How Do They Work? ⧂ - Spaceopedia
An orbit is a curved path in space that an object repeatedly makes as it goes around another larger object. This occurs because as an object (like a planet or moon) attempts to travel in a straight line through space, its path is curved towards the larger object (like the Sun) due to its mass and gravity.
Orbit | Astronomy, Physics & Mathematics | Britannica
3 天之前 · Orbit, in astronomy, path of a body revolving around an attracting centre of mass, as a planet around the Sun or a satellite around a planet. In the 17th century, Johannes Kepler and Isaac Newton discovered the basic physical laws governing orbits; in the 20th century, Albert Einstein’s general.
