Yes. Our solar system is part of the Milky Way galaxy.
It doesn't. The part of the Earth closest to the sun is the part of the Earth experiencing Winter.
The Earth is part of a larger system known as the Solar System, with the Sun roughly at the center, which the Earth orbits. The Solar System comprises the Sun, eight planets - one of which is Earth, and other objects. The solar system itself is also in orbit about the center of the galaxy (The Milky Way) which galaxy is part of a local grouping of galaxies, which is in turn part of a larger cluster of galaxies.
Big Bang, formation of galaxies, formation of sun, formation of earth.
Yes. The Earth, our Sun and indeed all planets, stars and galaxies are in constant motion.
No, galaxies do not change with the seasons because of Earth's movement around the Sun. The change in seasons on Earth is due to the tilt of its axis relative to its orbit around the Sun. Galaxies are vast collections of stars, gas, and dust that remain relatively unchanged on large timescales.
Nothing but the moon revolves around earth. Everything including the earth revolves around the sun. The Sun has many orbits which is what we are currently on. Our orbit of the sun. Hope I helped...
As the Earth rotates on it's axis, while on its orbit around the Sun, the sun's light can only strike that part of the earth directly facing the sun at any one time.
At night time the part of the Earth you are on, is facing away from the sun so it does not receive any sunlight. As the Earth turns around to face the sun it becomes morning.
Of course not. If it's the center of the Earth, it means that it's part of the Earth, not the sun.
what is the period when a given part of earth is facing the sun
The earth, the sun, stars, and galaxies emit infrared rays.
At any given time, the part of the Earth that is facing away from the Sun is dark. This is why we have day and night cycles as the Earth rotates on its axis.
