Final answer:
The Earth's intergalactic movement involves the Local Group moving towards a distant collection of galaxies, our solar system orbiting the Milky Way Galaxy, and the Earth rotating on its axis and revolving around the Sun.
Step-by-step explanation:
The Earth's intergalactic movement involves various factors.
First, the Local Group, which includes the Milky Way Galaxy, is moving towards an enormous collection of galaxies 45 million light-years away.
Additionally, our solar system, including the Sun and its family of planets, moons, asteroids, and comets, orbits the center of the Milky Way Galaxy.
This orbit is approximately circular, with a radius of 30,000 light-years and an orbital speed of 250 km/s.
Lastly, the Earth rotates on its axis and revolves around the Sun, causing day and night and the change of seasons.
