Does mass affect orbital period?
Short version: Yes, the orbital velocity is affected by the planet’s mass. In general, given two planets in the same exact orbit, the less massive planet will take longer to complete one period than the more massive planet.
Why does orbital period not depend on mass?
No, the mass of a body orbiting a second body is irrelevant in determining orbital parameters, as long as the first body is much larger than its satellite. You can see this reflected in Kepler’s third law: The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.
What determines the period of a satellite?
The period of a satellite (T) and the mean distance from the central body (R) are related by the following equation: The period, speed and acceleration of a satellite is only dependent upon the radius of orbit and the mass of the central body which the satellite is orbiting.
On what factors the orbital speed of satellite depends?
The orbital speed of the satellite depends on its altitude above the Earth. To maintain an orbit that is 35,786 km above the Earth, a satellite must orbit at the speed of about 11,300 km per hour. That orbital speed and distance permit the satellite to make one revolution in exactly 24 hours.
Does orbital velocity depend on the mass of the object?
The orbital velocity is independent of mass of orbiting body.
Does orbital speed depend on mass?
Assuming we are talking about the mass of the satellite (and not the mass of the body being orbited), mass does not affect the orbital speed.
How does orbital velocity of a satellite depends on the mass of the satellite?
Yes, the speed of a satellite does depend on the mass of the Earth. The total amount of (net) work done by gravity as a satellite makes a complete orbit is zero. The gravitational force has a component in the direction of the satellite’s motion as the satellite moves toward the Sun (or Earth, or whatever).
What is the orbital period of a GPS satellite?
Nominally the Global Positioning System (GPS) consists of 24 satellites (21+3 active spares). The satellites are in almost circular orbits approximately 20 000 km above the surface of the Earth. The siderial revolution period is almost precisely half a siderial day (11h 58m).
What determines the orbital period of a satellite in space?
The relationship between the satellite and the earth dictates the orbital period, but it is mostly dictated by the relative mass of the two objects. Given that the Earth is so much more massive than the satellite, the mass of the satellite is insignificant in comparison.
Is a satellite always in orbit around the Earth?
Strictly speaking the satellite is not in orbit around the Earth but is orbiting around the center of mass of the two combined masses (t This is an interesting question when you get close to it. The reality is that any two bodies with mass are always orbiting each other.
How do you calculate the motion of a satellite in space?
where G = 6.67 x 10-11 N m2/kg2, Mcentral = the mass of the central body about which the satellite orbits, and R = the average radius of orbit for the satellite. The final equation which is useful in describing the motion of satellites is Newton’s form of Kepler’s third law.
Why is the Earth in orbit around the Earth?
In essence, because both are simultaneously attracting each other, and that attraction is what keeps the satellite in orbit around the Earth, the Earth is also in orbit about the satellite. Strictly speaking the satellite is not in orbit around the Earth but is orbiting around the center of mass of the two combined masses (t
