The average distance between Saturn and the Sun is over 1.4 billion kilometers (9 AU). With an average orbital speed of 9.68 km/s, [6] it takes Saturn 10,759 Earth days (or about 29 + 1 ⁄ 2 years) [86] to finish one revolution around the Sun. [6] As a consequence, it forms a near 5:2 mean-motion resonance with Jupiter. [87]
In astronomy, the rotation period or spin period [1] of a celestial object (e.g., star, planet, moon, asteroid) has two definitions. The first one corresponds to the sidereal rotation period (or sidereal day ), i.e., the time that the object takes to complete a full rotation around its axis relative to the background stars ( inertial space ).
Every planet except Mercury and Saturn is known to possess at least 1 trojan. [161] [162] [163] The Jupiter trojan population is roughly equal to that of the asteroid belt. [164] After Jupiter, Neptune possesses the most confirmed trojans, at 28. [165]
Determining the length of a single day on a planet is usually pretty easy. You just pick a landmark and wait for it to reach the exact same point twice in its rotation and you have your answer ...
Distance of the outer limit of Oort cloud from the Sun (estimated, corresponds to 1.2 light-years) — Parsec: 206 265 — One parsec. The parsec is defined in terms of the astronomical unit, is used to measure distances beyond the scope of the Solar System and is about 3.26 light-years: 1 pc = 1 au/tan(1″) [60] [61] Proxima Centauri: 268 000 ...
The centre of the Milky Way is about 26 000 light-years away. [35] [36] 1 × 10 5 ly: The Milky Way is about 100 000 light-years across. 1.65 × 10 5 ly: R136a1, in the Large Magellanic Cloud, the most luminous star known at 8.7 million times the luminosity of the Sun, has an apparent magnitude 12.77, just brighter than 3C 273. 10 6: 2.5 × 10 6 ly
A Saturn return marks when the planet Saturn returns to the sign, and degree, it was in when you were born. This cycle takes anywhere between 27 and 30 years, and lasts for about three years.
Earth may have had a ring made up of a broken asteroid over 400 million years ago, a study finds. The Saturn-like feature could explain a climate shift at the time. ... around the planet about 466 ...
