Average orbital speed. 5.43 km/s [8] ... These resonances occur when Neptune's orbital period is a precise fraction of that of the object, such as 1:2, or 3:4. If ...
In gravitationally bound systems, the orbital speed of an astronomical body or object (e.g. planet, moon, artificial satellite, spacecraft, or star) is the speed at which it orbits around either the barycenter (the combined center of mass) or, if one body is much more massive than the other bodies of the system combined, its speed relative to the center of mass of the most massive body.
Mean orbital speed [4] km/s: ≈ 220 Axial tilt to the ecliptic: deg. 7.25 Axial tilt to the galactic plane: ... (Uranus and Neptune). When excluding the Sun, the ...
Neptune: 6.836 529 (9) × 10 ... The central body in an orbital system can be defined as ... v is the orbital speed, ω is the angular speed, and T is the orbital ...
The speed of the planet in the main orbit is constant. ... The orbital radius and angular velocity of the planet in the elliptical orbit will vary. ... Neptune 30. ...
Average orbital speed. 4.39 km/s [a] Inclination: ... At present, Triton's rotational axis is about 40° from Neptune's orbital plane, hence as Neptune orbits the Sun ...
Neptune was discovered in 1846 and is located 30 times farther from the sun than Earth. The planet's 164-year orbit takes it through some of the darkest and most remote regions of the outer solar ...
A relatively small extra delta-v above that needed to accelerate to the escape speed can result in a relatively large speed at infinity. Some orbital manoeuvres make use of this fact. For example, at a place where escape speed is 11.2 km/s, the addition of 0.4 km/s yields a hyperbolic excess speed of 3.02 km/s:
