Why is Earths orbital velocity slowest on July 5?
Earth's orbital velocity is slowest on July 5 because that is when Earth is at aphelion, its farthest point from the Sun in its elliptical orbit. At this point, the gravitational pull from the Sun is weaker, causing Earth to move more slowly in its orbit.
What is the speed of a satellite that moves in an eliptical orbit around the earth?
The speed of a satellite in an elliptical orbit around Earth varies depending on its distance from the planet. The satellite moves fastest at the point in its orbit closest to the Earth (perigee) and slowest at the point farthest from the Earth (apogee). The average speed of the satellite can be calculated using the vis-viva equation.
When does a planet move slowest in its orbit?
A planet moves slowest in its orbit when it is farthest away from the body it is orbiting, which is known as its aphelion. This is due to Kepler's second law of planetary motion, which states that a planet will move slower when it is farther from the body it orbits.
What planet moves around sun the slowest?
The planet that moves around the Sun the slowest is Neptune. Neptune takes about 165 Earth years to complete one orbit around the Sun.
What would happen to a satellite orbiting the earth if its velocity increased?
If a satellite's velocity increased while in orbit around Earth, it would move into a higher orbit, farther away from the planet. This would result in an elliptical orbit with a higher apogee (farthest point) and a lower perigee (closest point) compared to its original circular orbit.
