Polar orbit - Wikipedia
A polar orbit is one in which a satellite passes above or nearly above both poles of the body being orbited (usually a planet such as the Earth, but possibly another body such as the Moon or Sun) on each revolution.
Chapter 5: Planetary Orbits - NASA Science
Polar orbits are 90 degree inclination orbits, useful for spacecraft that carry out mapping or surveillance operations. Since the orbital plane is nominally fixed in inertial space, the planet rotates below a polar orbit, allowing the spacecraft low-altitude access to …

2020年3月30日 · Polar orbits are a type of low Earth orbit, typically between 200 to 1000 km in altitude. Satellites in polar orbits usually travel around Earth from, roughly, one pole to the other, rather than from west to east.
Polar Orbit – Definition & Detailed Explanation - Sentinel Mission
2024年3月22日 · A polar orbit is a type of orbit in which a satellite passes over the Earth’s poles as it orbits the planet. This means that the satellite’s path is perpendicular to the equator, allowing it to cover the entire surface of the Earth over time.
#29. Polar Orbiting Satellites - NASA
2001年11月25日 · The space shuttle avoids polar orbits, because flying through the aurora exposes astronauts to radiation and creates other problems. But for studying the aurora, Birkeland currents, polar rain and other phenomena related to the …

5 天之前 · Polar Orbit. Within 30 degrees of the Earth’s poles, the polar orbit is used for satellites providing reconnaissance, weather tracking, measuring atmospheric conditions, and long-term Earth observation. Sun-Synchronous Orbit (SSO)
Polar Orbit - (Astrophysics I) - Vocab, Definition, Explanations
A polar orbit allows satellites to pass over the Earth's poles, systematically covering different latitudes as the Earth rotates beneath them. This means that, over time, satellites in polar orbits can observe and collect data from every part of the Earth's surface.
Polar orbit | Britannica
…in a north-south direction, called polar orbits, can obtain more detailed data about changing atmospheric conditions. They also provide repetitive global coverage as Earth rotates beneath their orbit.
ESA - 4. The polar orbit - European Space Agency
As the name suggests, polar orbits pass over the Earth’s polar regions from north to south. The orbital track of the satellite does not have to cross the poles exactly for an orbit to be called polar, an orbit which passes within 20 to 30 degrees of the poles is still classed as a polar orbit.
Polar Orbit - Mission Juno
An orbit that takes Juno over Jupiter’s north and south poles is the best way to map the entire planet. Called a polar orbit, this path allows Juno to pass directly over any longitude, so as Jupiter rotates, Juno can eventually cover the entire surface.
