Typical Sun-synchronous orbits around Earth are about 600–800 km (370–500 mi) in altitude, with periods in the 96–100-minute range, and inclinations of around 98°. This is slightly retrograde compared to the direction of Earth's rotation: 0° represents an equatorial orbit, and 90° represents a polar orbit.
In astronomy, Kepler's laws of planetary motion, published by Johannes Kepler in 1609 (except the third law, and was fully published in 1619), describe the orbits of planets around the Sun. These laws replaced circular orbits and epicycles in the heliocentric theory of Nicolaus Copernicus with elliptical orbits and explained how planetary ...
The Sun Chronicle (formerly The Attleboro Sun and the Evening Chronicle) is a daily newspaper in Attleboro, Massachusetts, United States.Most of its readers are in Attleboro and North Attleborough, Massachusetts, but it also covers nearby Foxborough, Mansfield, Norfolk, Norton, Plainville, Rehoboth, Seekonk, and Wrentham, Massachusetts, as well as North Eastern Rhode Island.
In comparison, the sun orbits around the Milky Way at a rate of 450,000 miles per hour (200 kilometers per second). ... “I calculated the mass of this object to be approximately 8% of the mass ...
The Sun orbits the Galactic Center at a distance of 24,000 to 28,000 light-years. From Earth, it is 1 astronomical unit (1.496 × 10 8 km) or about 8 light-minutes away. Its diameter is about 1,391,400 km (864,600 mi), 109 times that of Earth. Its mass is about 330,000 times that of Earth, making up about 99.86% of the total mass of the Solar ...
Euler diagram showing the types of bodies orbiting the Sun. The following is a list of Solar System objects by orbit, ordered by increasing distance from the Sun. Most named objects in this list have a diameter of 500 km or more. The Sun, a spectral class G2V main-sequence star; The inner Solar System and the terrestrial planets. 2021 PH27; Mercury

Most orbits in the Solar System have a much lower eccentricity and precess at a much slower rate, making them nearly circular and stationary. The main orbital elements (or parameters). The line of apsides is shown in blue, and denoted by ω. The apsidal precession is the rate of change of ω through time, dω / dt .
