The song says that we are "thirty thousand light years from galactic central point", again correct to within one significant figure of 25,000 light years from the centre of the Milky Way. [12] The song also states that the galaxy is "a hundred thousand light years side to side".
The galactic year, also known as a cosmic year, is the duration of time required for the Sun to orbit once around the center of the Milky Way Galaxy. [1] One galactic year is approximately 225 million Earth years. [2]
The apex of the Sun's way, or the solar apex, is the direction that the Sun travels through space in the Milky Way. The general direction of the Sun's Galactic motion is towards the star Vega near the constellation of Hercules, at an angle of roughly 60 sky degrees to the direction of the Galactic Center. The Sun's orbit about the Milky Way is ...
The Solar System traces out a sinusoidal path in its orbit around the galactic center. Using Galactic North as the initial frame of reference, the Earth and Sun rotate counterclockwise, and the Earth revolves in a counterclockwise direction around the Sun. However, the Sun and its satellites revolve CLOCKWISE around the Milky Way.
The Sun is part of one of the Milky Way's outer spiral arms, known as the Orion–Cygnus Arm or Local Spur. [270] [271] It is a member of the thin disk population of stars orbiting close to the galactic plane. [272] Its speed around the center of the Milky Way is about 220 km/s, so that it completes one revolution every 240 million years. [269]
The Sun's idealized orbit around the Galactic Center in an artist's top-down depiction of the current layout of the Milky Way. The Milky Way is moving with respect to the cosmic microwave background radiation (CMB) in the direction of the constellation Hydra with a speed of 550 km/s.
"Galileo, Galileo!": Sydney and Jet are having a hard time explaining to Mindy that the Sun doesn't move - the Earth is moving around the Sun, so the Sun seems to move. Then Sean comes over dressed as his science hero Galileo, getting ready to do a school report. Mindy asks "Galileo" to explain why the Sun seems to move, and Sean practices for ...
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. Mercury
