The Milky Way is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.
Longitudinal lines of the galactic coordinate system. A galactic quadrant, or quadrant of the Galaxy, is one of four circular sectors in the division of the Milky Way Galaxy. Numbered quadrants and sectors of constellations. Quadrants as starcharts, with most prominent stars marked.
Diagram of the Milky Way, with galactic features and the relative position of the Solar System labelled. The Solar System is located in the Milky Way, a barred spiral galaxy with a diameter of about 100,000 light-years containing more than 100 billion stars.
1785 — William Herschel carried the first attempt to describe the shape of the Milky Way and the position of the Sun in it by carefully counting the number of stars in different regions of the sky. He produced a diagram of the shape of the galaxy with the solar system close to the center.
The Milky Way is a barred spiral, although the bar itself is difficult to observe from Earth's current position within the galactic disc. The most convincing evidence for the stars forming a bar in the Galactic Center comes from several recent surveys, including the Spitzer Space Telescope.
Location of the Solar System within the Milky Way. The Solar System travels alone through the Milky Way in a circular orbit approximately 30,000 light years from the Galactic Center. Its speed is about 220 km/s. The period required for the Solar System to complete one revolution around the Galactic Center, the galactic year, is in the range of ...
A model of galaxy based on a general relativity metric was also proposed, showing that the rotation curves for the Milky Way, NGC 3031, NGC 3198 and NGC 7331 are consistent with the mass density distributions of the visible matter, avoiding the need for a massive halo of exotic dark matter.
A six-planet solar system in perfect synchrony has been found in the Milky Way. CAPE CANAVERAL, Fla. (AP) — Astronomers have discovered a rare in-sync solar system with six planets moving like a ...
One orbital period of the Solar System lasts between 225 and 250 million years. Milky Way Galaxy: 30,000 pc 9.26×10 17: 17.97: Our home galaxy, composed of 200 billion to 400 billion stars and filled with the interstellar medium. Milky Way subgroup: 840,500 pc 2.59×10 19: 19.41
Whirlpool Galaxy. The Whirlpool Galaxy, also known as Messier 51a ( M51a) or NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus. [6] [7] [8] It lies in the constellation Canes Venatici, and was the first galaxy to be classified as a spiral galaxy. [9]
