Question

It takes the Sun 225-250 million years to do one revolution of the Milky Way. How fast does the Sun travel?
a) 220 km in a second
b) 220 km in a minute
c) 220 km in an hour
d) 220 km in a year​

Answer 1

Answer:

220 km in an year

option (D) is correct.

Answer 2

Answer:

he Sun travels 220 km in a second

Explanation:

• In actuality, the Sun is pulling us throughout the galaxy at a pace of approximately 800 000 km/h, and one orbit takes approximately 250 million years to complete.
• That suggests that since our Solar System's formation around 4.5 billion years ago, it has made approximately 18 complete rounds.
• The solar rotates across the Milky Way Galaxy at a pace of 220 kilometers consistent with a second.

CALCULATION:

1 light year =  9.461 ×$10^1^2$ km

( assuming a distance of 30,000 light-years)

• total distance traveled for one revolution is

= 30000 × 9.461 ×$10^1^2$ km

• total time = 225 million years.

therefore, the speed of the sun is = D / T

                                                        = 220 km/s (approx).
