The ___________ is the galaxy that is containing our solar system
Correct Answer
B. Milky way
Explanation
The Milky Way is the correct answer because it is the galaxy that contains our solar system. The term "solar system" refers to the collection of planets, moons, and other celestial bodies that orbit around our sun. The Milky Way is a spiral galaxy that is home to billions of stars, including our sun. It is named after its appearance as a hazy band of light in the night sky.
2.
Milky way in latin is ____________
Correct Answer
A. Lactic
Explanation
The correct answer is "Lactea." This is because "Lactea" is the Latin word for "Milky way." The word "lactic" refers to something related to milk, but it is not the Latin term for the Milky Way. "Milksi" is not a valid Latin word, and "None of the above" is incorrect because "Lactea" is the correct Latin term for the Milky Way.
3.
_____________ first resolved the band of light into individual stars with telescope in 1610.
Correct Answer
A. Galileo
Explanation
Galileo was the one who first resolved the band of light into individual stars with a telescope in 1610. He made significant advancements in astronomy and used his telescope to observe celestial objects, including the Milky Way. This breakthrough allowed him to see that the band of light was actually composed of countless individual stars, challenging the prevailing belief that it was a continuous celestial object. Galileo's observations and discoveries revolutionized our understanding of the universe and laid the foundation for modern astronomy.
4.
The escape velocity at Sun's position is __________Km/s
Correct Answer
B. 550
Explanation
The escape velocity at the Sun's position is 550 Km/s. Escape velocity is the minimum velocity required for an object to escape the gravitational pull of a celestial body. Since the Sun has a very strong gravitational pull, a high escape velocity is needed to overcome it. Therefore, the correct answer is 550 Km/s.
5.
The solar system is Located within the ________________
Correct Answer
C. Disk
Explanation
The correct answer is "Disk." The solar system is located within a disk-shaped region called the Milky Way galaxy. The Milky Way is a spiral galaxy, and the solar system is situated in one of its spiral arms. The disk-shaped structure of the galaxy is where most of the stars, including our Sun, are located.
6.
The mass of milky is called ____________
Correct Answer
C. Dark matter
7.
The rotation period at the position of the sun is about ________million years
Correct Answer
D. 240
Explanation
The rotation period at the position of the sun is about 240 million years. This refers to the time it takes for the sun to complete one full rotation on its axis.
8.
Milky way as a whole moves at a velocity of about ________km/s
Correct Answer
C. 600
Explanation
The correct answer is 600 km/s. This refers to the velocity at which the Milky Way as a whole moves. The Milky Way is not stationary, but rather it is in constant motion. It is estimated that the Milky Way moves through space at a speed of approximately 600 kilometers per second. This movement is influenced by various factors, including the gravitational pull of nearby galaxies and the expansion of the universe.
9.
Milky way has several _____________
Correct Answer
A. Satellite galaxies
Explanation
The Milky Way has several satellite galaxies. Satellite galaxies are smaller galaxies that orbit around larger galaxies, such as the Milky Way. These satellite galaxies are gravitationally bound to the Milky Way and are influenced by its gravitational pull. They are not stars or moons, but separate entities that are part of the larger galactic system. Therefore, the correct answer is satellite galaxies.
10.
Milky way is a component of ______________
Correct Answer
A. Virgo supercluster
Explanation
The Milky Way is a component of the Virgo supercluster, which is a vast collection of galaxies that includes our own galaxy. The Virgo supercluster is one of the largest known structures in the universe, consisting of several galaxy clusters and groups. Our galaxy, the Milky Way, is just one of the many galaxies within this supercluster, highlighting its immense size and complexity.
