Earth’s speed puts asteroids to shame; check out how fast it moves in space

tech.hindustantimes.com:

The Earth, like any other celestial body, is in constant motion. In fact, Earth has quite a few motions due to the gravitational forces that act upon it. The Earth spins across its axis, it revolves around the Sun, it moves through the galaxy as a part of the solar system, it also moves through the local group as a part of the Milky way and of course, the local group itself moves through the larger universe carrying the Earth. So, you see, it is not really easy to answer how fast does the Earth move in space? But we have tried to find out how fast the Earth will appear to a space body outside of our local group, in distant space. And the answer is pretty shocking. The tiny pebbles we call asteroids seem like snails compared to our blue-green planet.

But before getting to the answer, it is important to dissect Earth’s motion across all the different axes to accurately find out the real speed of the Earth. We have to do this difficult and time-consuming task as we do not have an outsider’s perspective to really see how fast the Earth moves. No human or a human-built technology has ever left our galaxy, much less the local group to neutrally observe the speed of Earth. But there is no need to be disheartened. Scientists have observed various parameters and calculated an estimated speed of Earth in space.

Breaking it down, we know the Earth’s radius is around 6371 kilometers, and considering Earth completes an entire rotation in 24 hours, its rotational speed is around 1676 km/h or 0.47 km/s near the equator. But it is negligible to how fast the Earth moves around the Sun. Calculations suggest that at its fastest, the speed of Earth around the Sun is 30.29 km/s. It is 60 times faster than its rotational speed. Also an
