Question

What is the shape of the Milky Way Galaxy?
A. Circular
B. Spiral
C. Elliptical
D. Irregular

Answer 1

Hint: 1. The Milky Way is the galaxy that comprises our Solar System, defining the presence of the galaxy from Earth with the name: a hazy band of light seen in the night sky created by stars that can not be distinguished individually by the naked eye.
2. The observable diameter is measured at 1.9 million light-years of milky way. It has many stars in it. Sun is a part of the milky way.

Complete answer:
1. The Milky Way is a barred spiral galaxy with an average visible diameter of 1.9 million light-years (ly), giving or taking 0.4 million light years It is estimated to contain 100-400 billion stars. The halo of dark matter around the Milky Way will take up to 2 million light years. The Solar System is located from the Galactic Center at a radius of about 27,000 light-years.
2. Stars and gases are orbiting at about 220 kilometres per second at a large variety of distances from the Galactic Center. The constant speed of rotation violates the laws of Keplerian dynamics and indicates that a great deal of (about 90 percent )
Option A is an incorrect answer as the Milky Way is not circular in shape.
Option B is correct answer as Milky Way is spiral in shape
Option C is incorrect answer as Milky Way is not elliptical in shape
Option D is an incorrect answer as the Milky Way is not irregular in shape.

Hence the correct answer is option B.

Note: 1. There are many satellite galaxies in the Milky Way and it is part of the Local Community of Galaxies, which is part of the Virgo Supercluster, a member of the Laniakea Supercluster itself.
2. Our solar system consists of the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, dwarf planets like Pluto, hundreds of moons and millions of asteroids, comets and meteoroids. Our solar system consists of our star, the Sun, and everything bound to it by gravity. This is a portion of the Milky Way.
