How fast is the Earth traveling through space?

2 Answers

Answer:

Earth is orbiting the Sun at 29.8 kilometer per second.

Explanation:

As solar system is going around milky way galaxy this motion is also to be considered.This speed is 220 kilometer/second.

Answer:

Velocity is a vector. Speed is its magnitude. Earth's velocity vector rotates through #360^o# in one year. Its relative average speed over a year is nearly 29.78 km.sec.

Explanation:

The averaging here is like averaging relative speed of Moon with respect to the Earth The Moon is ahead of the Earth in about a fortnight and behind the Earth (in regression) for the next fortnight..

Likewise, the Earth is ahead of the Sun in a half year behind for the next half, relating to the orbit of the Sun about the center of Milky Way. There is no preferred space in space, All motion is relative to one another.

Algebraically, there is a maximum and a minimum for the speed of the Earth relative to the center of the Milky Way. Yet, the angular speed 2.5 E-08 radian/year of the Sun about MW center is quite small compared to the angular speed 6.28 radian/year of the Earth about the Sun

Contribution of the speed of the recession of Milky Way in space to the Earth's speed in space is much smaller in magnitude.

So, there is reason to state that the 4-sd approximation 29,78 km/sec to its average speed about the Sun is the average speed of the Earth in space. The other contributions are insignificant. .
