The orbital plane of a revolving body is the geometric plane in which its orbit lies. Three non- collinear points in space suffice to determine an orbital plane. A common example would be the positions of the centers of a massive body (host) and of an orbiting celestial body at two different times/points of its orbit.

Radian Aerospace is building a next-generation spaceplane planned to be the world's first single-stage-to-orbit, truly reusable space vehicle operating in Low Earth Orbit.

The planet's orbit lies in a plane, called the orbital plane. The point on the orbit closest to the attracting body is the periapsis. The point farthest from the attracting body is called the apoapsis.

2024年4月4日 · An orbital plane is the flat, disk-shaped space that connects the center of the object being orbited with the center of the orbiting objects.

Orbital inclination measures the tilt of an object's orbit around a celestial body. It is expressed as the angle between a reference plane and the orbital plane or axis of direction of the orbiting object.

2024年11月4日 · 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.

2010年7月7日 · 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. Many planets have moons that orbit them. A satellite …

Orbital mechanics, also called flight mechanics, is the study of the motions of artificial satellites and space vehicles moving under the influence of forces such as gravity, atmospheric drag, thrust, etc. Orbital mechanics is a modern offshoot of celestial mechanics which is the study of the motions of natural celestial bodies such as the moon ...

2025年2月21日 · The United States Space Force released the first public photo taken by X-37B space plane in orbit, showing the vehicle high above Earth.

2024年12月18日 · An orbital plane is a flat, disk-shaped space that connects the center of the object being orbited with the center of orbiting objects. Because all planets in our solar system share a similar orbital plane, planets don't collide.

An orbital plane is the geometric plane of an orbit. It is described by its difference from a reference plane. The reference plane for the Solar System is usually the Earth 's orbital plane. This defines the ecliptic, the path on the celestial sphere that the Sun appears to follow over a year.

All of the planets, comets, and asteroids in the solar system are in orbit around the Sun. All of those orbits line up with each other making a kind of flat disk called the orbital plane. The planets all orbit on or near one plane in space like the picture above.

1981年8月4日 · The planets all orbit the Sun in roughly the same plane, known as the ecliptic (the plane of the Earth's orbit), and in the same direction, counterclockwise as viewed from the north ecliptic pole. Because of gravitational torques from the other planets, the ecliptic is not inertially fixed in space, and so dynamicists often use the invariable ...

2025年2月21日 · The X-37B, designed to function somewhere between a plane and a satellite, is on a heavily elliptical orbit, according to details released by Space Force.

This study investigates the feasibility of performing orbit plane rotations during aerocapture maneuvers. Three-degrees-of-freedom bounding trajectories at Mars are propagated for a range of vehicle lift-to-drag ratios 퐿/퐷 and hyperbolic arrival velocities 푣∞ . The results show that the maximum plane rotation achievable increases with ...

Nodal precession is the precession of the orbital plane of a satellite around the rotational axis of an astronomical body such as Earth. This precession is due to the non-spherical nature of a rotating body, which creates a non-uniform gravitational field.

2025年3月8日 · Space Force’s secretive X-37B plane has spent more than 900 days in orbit Space Force’s secretive X-37B plane has spent more than 900 days in orbit By Nicholas Slayton Posted on Nov 6, 2022

2020年3月30日 · What is an orbit? An orbit is the curved path that an object in space (like a star, planet, moon, asteroid or spacecraft) follows around another object due to gravity. Gravity pulls objects with mass towards each other. If this attraction brings them together with enough momentum, they can start to orbit each other.

2025年3月10日 · The U.S. military's top-secret X-37B space plane has returned from a mysterious 434-day mission in orbit. The enigmatic mission 'broke new ground' for reusable space technology, according to the U ...

2023年6月8日 · Orbital inclination refers to the angle between the orbital plane of a planet and a reference plane, typically the plane of the celestial equator or the ecliptic plane. It measures how tilted or inclined the planet's orbit is relative to the reference plane.

Orbiting spacecraft are subject to a variety of environments. Knowledge of the orbit is required to quantify the solar, albedo and planetary (also called outgoing longwave radiation, or OLR) …

2 天之前 · The spin-orbit torque (SOT) derived from the spin Hall effect (SHE) or Rashba-Edelstein effect (REE) has been shown to enable the electrical switching of magnetization. ... a large number of methods have been employed to obtain field-free magnetization switching such as introducing an in-plane effective field through adjacent (anti ...

Orbital inclination change is an orbital maneuver aimed at changing the inclination of an orbiting body's orbit. This maneuver is also known as an orbital plane change as the plane of the orbit is tipped.
