The sun's orbit around the galaxy is expected to be roughly elliptical with the addition of perturbations due to the galactic spiral arms and non-uniform mass distributions. The Sun and its planets take a period of 225 million years to revolve around the galactic center.


The period of time is called a cosmic year.

The Sun has completed about 20 orbits since the solar system was formed. One of the stars has been observed for its full orbit of 15.6 years. Astronomers have calculated that it takes the Sun 226 million years to completely orbit around the center of the Milky Way. The "galactic year", the period of time for the Sun to completely orbit the center of the Milky Way galaxy, is estimated at from 225 to 250 million Earth years. Asked in Planet Jupiter It is approximately 200 km/sec, which allows us to estimate the period of the Sun's orbit around the Galactic Center in the following way: Assume the Sun is following a circular orbit with radius 8,000 parsecs. Based on a distance of 30,000 light years and a speed of 220 km/s, the Sun's orbit around the center of the Milky Way once every 225 million years. The Solar System moves through the galaxy with about a 60° angle between the galactic plane and the planetary orbital plane. One galactic rotation at our distance from the galactic center takes about 220 million years. The Sun orbits around the galactic center of the Milky Way Galaxy and takes about 230 million Earth years to complete one Galactic Year. The Galactic Center, which sits at the center of our Milky Way Galaxy, is the source of energetic particles that bathe the Earth. Calculate the circumference of the Sun's orbit: c = 2 π r = (2 π) * (8000 pc) * (3.1 x 10 13 km / pc) = 1.6 x 10 18 km. During the 4.6 billion years that the Sun has been in existence, it has gone around the center just over 20 times. In other words, that last time that the Sun was in its … The general direction of the sun's galactic motion is towards the star Vega near the constellation of Hercules, at an angle of roughly 86 degrees to the direction of the galactic center. With the recent years of the Sun being fairly quiet and Earth’s magnetic field weakening a bit, these energetic particles (infrared and gamma particles) have been able to make their way into the Earth’s energy field. Its closest approach takes it to a distance of only 124 AU or about 17 light-hours from the black hole. The Sun has orbited the galaxy, more than 20 times during its 5 billion year lifetime. Neptune takes 164 earth years to orbit the sun .60,189 earth days and 1979 earth months to orbit the sun. The motions of the period are studied by measuring the positions of lines in the galaxy spectra. The planets orbit the Sun, roughly in the same plane.
