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] The elliptical orbit of Saturn is inclined 2.48° relative to the orbital plane of the Earth. [6]
One complete orbit takes 365.256 days (1 sidereal year), during which time Earth has traveled 940 million km (584 million mi). [2] Ignoring the influence of other Solar System bodies, Earth's orbit, also called Earth's revolution, is an ellipse with the Earth–Sun barycenter as one focus with a current eccentricity of 0.0167. Since this value ...
At the time of J1407b's discovery, V1400 Centauri was known as "J1407", which is the shortened form of the star's full SuperWASP catalogue designation 1SWASP J140747.93–394542.6. [ 4 ] : 5 This designation shows the star's location in the sky in equatorial coordinates .

For instance, a small body in circular orbit 10.5 cm above the surface of a sphere of tungsten half a metre in radius would travel at slightly more than 1 mm/s, completing an orbit every hour. If the same sphere were made of lead the small body would need to orbit just 6.7 mm above the surface for sustaining the same orbital period.
Saturn's orbit plane is inclined 2.485 degrees relative to Earth's, and Jupiter's is inclined 1.303 degrees. The ascending nodes of both planets are similar (100.6 degrees for Jupiter and 113.7 degrees for Saturn), meaning if Saturn is above or below Earth's orbital plane Jupiter usually is too. Because these nodes align so well it would be ...
The holiday season holds a special gift, as skygazers on Earth will be treated to a great conjunction of the planets Jupiter and Saturn. Using binoculars or a backyard telescope, it will not only ...
Given the different Sun incidence in different positions in the orbit, it is necessary to define a standard point of the orbit of the planet, to define the planet position in the orbit at each moment of the year w.r.t such point; this point is called with several names: vernal equinox, spring equinox, March equinox, all equivalent, and named considering northern hemisphere seasons.
