The sun, like all the stars in the night sky, appears to be motionless in the sky. However, the sun is actually in constant motion, just like all of the other stars. The sun orbits the center of our Milky Way galaxy at a speed of about 220km/sec or 490,000 miles/hr.
The sun is also moving through space at a speed of about 19 miles/sec away from the constellation Hercules.
In addition to these motions, the sun is spinning on its own axis. It rotates once at its equator every 25 to 28 days. The extreme temperatures caused by the sun’s heat cause intense solar wind that spreads across the entire solar system sending out streams of charged particles that affect other planets as well.
So, while it may seem that the sun is stationary in the sky, it is actually moving in a variety of ways.

Does our sun revolve around anything?
No, our sun does not revolve around anything. In fact, the sun is the center of our solar system and all other planets revolve around it. The eight planets, or the eight major bodies in our solar system, including Earth, revolve around the sun in elliptical orbits.
The sun is also a star, just like many others that exist in the Milky Way universe. All the stars in our Milky Way galaxy revolve around a common point because of the gravitational pull of their mass, which is the center of the Milky way.
Therefore, our sun is merely one of many stars that revolve around the center of the Milky way.
What keeps the sun spinning?
The sun’s rotation is approximately driven by “conservation of angular momentum”, which is a fundamental law of physics that states that the total angular momentum (rotational motion) of an object will remain constant unless an external torque (twisting force) is applied to it.
The sun was formed as a rotating cloud of gas and dust, and so when it contracted and flattened to form the disk-like shape of the sun, according to the conservation of angular momentum, it kept spinning even faster as its size decreased – much like a spinning ice skater who brings their arms close in to spin faster.
In addition to the sun’s initial rotation, there are other forces that help to keep the sun spinning, such as the interaction of its magnetic field with the solar wind flow, tidal forces from the gravitational tug of the planets and the turbulence within the sun’s convection zone.
Why doesn’t the sun move?
The sun may appear to not be moving, but in actuality it rotates on an axis and revolves around the Milky Way galaxy, along with the planets and other stars. Although the sun appears stationary, it is in fact constantly moving.
From the perspective of an observer on Earth, the sun appears stationary because it revolves around the galaxy at the same speed that the Earth is revolving around it. If the Earth rotated faster, or slower, than the speed of its revolution then the sun would appear to move through the sky.
This means that the sun is constantly in motion, even if it appears still from Earth.
Will the Earth ever stop rotating around the sun?
No, the Earth will not stop rotating around the sun. This is because the Earth’s orbit around the sun is determined by its angular momentum. Angular momentum is a physical quantity that describes how much an object is rotating around an axis – an object with more angular momentum will move faster and an object with less angular momentum will move slower.
As the Earth orbits the sun, it is constantly exchanging momentum with the rest of the universe, but this does not affect its orbit. As a result, the Earth will continue to orbit the sun for as long as it maintains its angular momentum.
However, this angular momentum could potentially be changed over very long periods of time if enough mass were inserted into or taken out of the Earth’s orbit.
Does the sun rotate or revolve or both?
The sun rotates on its axis and revolves around the center of the Milky Way galaxy. In terms of its rotation, the sun takes approximately 25-35 days to rotate fully on its axis; however, the sun’s polar regions rotate more slowly than its equator.
The sun’s revolution around the center of the Milky Way, which is its orbit, takes around 250 million years to complete. This revolution is due to the gravitational pull of the other stars in the galaxy, which cause the sun and all the other planets in the solar system to orbit around the galaxy.
Is the sun rotating around a black hole?
No, the sun is not rotating around a black hole. This is because the sun is located in the Milky Way, which is a barred spiral galaxy, and it is located in the Orion Arm of the galaxy, which is about 26,000 light years from the center of our galaxy.
In the center of our galaxy there is a supermassive black hole, and the stars, including the sun, are orbiting around it. The sun is orbiting about 220 km/sec, which is roughly 830,000 miles per hour and it will take about 250 million years for the sun to make one rotation around the Milky Way’s core.
The sun is so far away from the black hole at the center of our galaxy that it would take a very long journey for the sun to actually rotate around it.
Why the Sun is not moving?
The Sun is the center of our Solar System, and it appears to not be moving because all of the planets, asteroids, and other objects in our Solar System all orbit around it. The Sun’s gravity, which is caused by its immense mass, is what gives all these objects their orbital velocity and keeps them in motion.
The steady force of the Sun’s gravity causes all of the planets to orbit around it, but the Sun itself does not move, since it does not have anything else to orbit around. So, for all intents and purposes, it can be said that the Sun is not moving relative to the other objects in our Solar System.
What holds the Sun up in the sky?
The Sun in our solar system is held in the sky by the force of gravity. It has been orbiting around the center of the Milky Way galaxy for billions of years due to this powerful force. The Sun’s gravity is so great that it is able to counteract the pull of the other planets and other stars in the Milky Way.
This means that the Sun has been able to stay at a constant distance from the center of the Milky Way, giving us the beautiful, consistent sunrises and sunsets that we so enjoy. So, simply put, it is the force of gravity that holds the Sun up in the sky.
Does the Sun rise in the same spot every day?
No, the Sun does not rise in the same spot every day. The Earth is constantly rotating and its motion affects the appearance and location of the Sun each morning. The Sun appears to travel in an arc across the sky, rising and setting at different positions in the horizon.
This is because the Sun actually orbits the Earth, rather than the Earth circling the Sun. As the Earth rotates, the Sun changes its position in the horizon with respect to observers. Additionally, the tilt of the Earth’s axis and its revolution around the Sun also affect the Sun’s position in relation to the horizon.
Why can’t you see the sun in space?
You can’t see the sun in space because even though we are orbiting the sun, space is a vacuum and the sun’s light can’t travel through a vacuum. Light can only travel through mediums, like air or water.
Therefore, in space, the sun’s rays can’t reach you to make it visible because there is no air or other mediums in a vacuum. Also, space is simply too far away from Earth for the sun’s light to reach us.
Even though the sun is very bright compared to other stars, the distance between us and the sun is so vast that if you were in space, you wouldn’t be able to see it.
Will the sun ever burn out?
No, the sun will not “burn out” in the same way that a normal star or candle burns out. The sun is a main sequence star, meaning it is in the longest and most stable stage of its life. This stage is the result of the balance between the inward pull of gravity and the outward push of the sun’s nuclear fusion.
Instead of “burning out” the sun will ultimately evolve into a red giant star, becoming so large that it will engulf the inner planets of the solar system, including Earth. Eventually, the sun will shrink down to a white dwarf star and spend the rest of its days slowly cooling off until it is eventually a cold, dark, dead star.
What keeps the Earth rotating the Sun?
The Earth’s rotation around the Sun is maintained by a gravitational force from the Sun that attracts the Earth and causes it to orbit. This gravitational force is created by the fact that the Sun is much more massive than the Earth, so its gravitational force is much larger.
This force acts on the Earth as a centripetal force, meaning it pulls the Earth towards the Sun, causing the Earth to move in a curved path around it. This path is known as the Earth’s orbit. As the Earth moves in its orbit around the Sun, it is constantly being pulled towards the Sun by its gravity and this causes it to continue orbiting around it.
The force of the Sun’s gravity is so strong that it causes the Earth to be held in its orbit and maintain its rotation.
