2. MILKY WAY GALAXY

3. INRODUCTION: The Milky Way is the galaxy that includes our 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. The term Milky Way is a translation of the Latin via lactea, from the Greek meaning “milky circle”. Age: 13.61 billion years Radius : 52,850 light years Escape velocity: 550 km/s Absolute magnitude: -21 Number of stars: 100–400 billion Right ascension: 17h 45m 40.0409s Constellations: Orion, Sagittarius, Scorpius, Canis Major, Carina, Ara

4. INTERESTING FACTS: The Milky Way is a barred spiral galaxy with an estimated visible diameter of 100,000–200,000 light-years. Recent simulations suggest that a dark matter disk, also containing some visible stars, may extend up to a diameter of almost 2 million light-years. The galactic center is an intense radio source known as Sagittarius A*, a supermassive black hole of 4.100 (± 0.034) million solar masses. Stars and gases at a wide range of distances from the Galactic Center orbit at approximately 220 kilometers per second. The constant rotational speed appears to contradict the laws of Keplerian dynamics and suggests that much (about 90%) of the mass of the Milky Way is invisible to telescopes, neither emitting nor absorbing electromagnetic radiation. This conjectural mass has been termed "dark matter

5. It is estimated to contain 100–400 billion stars The Solar System is located at a radius of about 27,000 light-years from the Galactic Center . The galactic center is an intense radio source known as Sagittarius A*, a supermassive black hole of 4.100 (± 0.034) million solar masses.
