Ngắm bầu trời sao lung linh, huyền ảo
31 Jan, 2015
In this stabilized time-lapse, the stars' position in the night sky is fixed so you can get a sense of our planet's movement through space. And now it's time for some mind-boggling (không thể tin được) figures:
– Earth rotates around its axis (at the Equator (đường Xích đạo)) at roughly 460 meters/second (503 yards/second)
– Earth orbits around our Sun at about 107,826 km/h (67,000 mph)
– Our solar system whirls around the center of the Milky Way galaxy roughly 788,579 km/h (490,000 mph)
You can read more about how fast Earth is moving in comparison to other objects at Scientific American.
