No. The speed of any orbiting body depends only on the energy of its orbit, meaning mainly its distance
from the central body.
When a Space Shuttle astronaut performs a 'space walk', and momentarily unhooks his feet from the
hull of the shuttle, he and the shuttle are both in earth orbit. The astronaut and the shuttle have the
same orbital speed, and they stay close together, even though the shuttle has somewhat more mass
than the astronaut has.

A satellite is 200 miles above the earth It has a mass of 150 kg If the mass of the satellite were tripled?
You don't really have a question here. If the satellite is in orbit, the mass is essentially irrelevant; it wouldn't change the speed of the orbit or the altitude. A larger satellite mass WOULD HAVE required more fuel and more energy to LAUNCH it, but once in orbit, it will stay there. The only exception would be an exceptionally large, light satellite. There is still some minuscule traces of atmosphere at 200 miles, and a large, light satellite would be slowed by air friction much more than a small dense satellite would. This is what caused the "ECHO" satellite - essentially a silvered mylar balloon inflated in orbit as a primitive reflector comsat - to deorbit.
Triple earth's mass effect its orbit?
The earth's mass has no effect on its orbit. An astronaut on a "space walk" hovering over the space shuttle's cargo bay is in the same earth-orbit as the shuttle itself is, although his mass is much less than the shuttle's mass. At the same time, the shuttle and the astronaut are both in the same solar orbit as the earth is, although each of them has quite a bit less mass than the earth has.
What would happen if the inertia of the earth was increased without he sun's gravity increasing?
Inertia is measured by an object's mass. The Earth would still go around in the same orbit, because the orbit does not depend on the mass of a planet. "Inertia" is sometimes used to mean "momentum". That's mass times velocity. If the Earth's velocity increased then it would move further from the Sun. <<>> The point is that "inertia" is a nonscienific word that is used to describe different things by different people and it's best to use "mass" or "momentum" depending on what is meant.
What are the 3 factors of weight?
The mass of the object, the mass of the object that is attracting it and the distance between their centres of gravity.So your weight on the moon will depend on your mass, the moon's mass and the distance from your centre of gravity to the moon's.The mass of the object, the mass of the object that is attracting it and the distance between their centres of gravity.So your weight on the moon will depend on your mass, the moon's mass and the distance from your centre of gravity to the moon's.The mass of the object, the mass of the object that is attracting it and the distance between their centres of gravity.So your weight on the moon will depend on your mass, the moon's mass and the distance from your centre of gravity to the moon's.The mass of the object, the mass of the object that is attracting it and the distance between their centres of gravity.So your weight on the moon will depend on your mass, the moon's mass and the distance from your centre of gravity to the moon's.
What are the forces that act on an astronaut in outer space?
Work is done whenever the given two conditions are satisfied: (i) A force acts on the body. (ii) There is a displacement of the body by the application of force in or opposite to the direction of force. If the direction of force is perpendicular to displacement, then the work done is zero. If the satellite is in a perfectly circular orbit, then the force of gravity is always perpendicular to the satellite's velocity, and gravity never does any work. If the orbit isn't circular, then there is a radial component of velocity at most points in the orbit, and some gravitational acceleration, work, etc., but those are exactly matched by negative values at other points in the orbit, and the total over a complete orbit is zero again.
If the mass of a statellite is doubled while the radius of its orbit remains constant then the speed of the satellite is increased by how much?
The velocity at which the satellite was launched would have to be increased in order for it to maintain the same orbit. So the speed would be increased.

Which force keeps a satellite in orbit?
The mutual gravitational attraction between the satellite's mass and the earth's mass. Short answer: The force of gravity.
Why is kinetic energy a constant for a satellite in circular orbit?
On account of the way gravity works, any satellite in any orbit of any shape moves faster when it's nearer the central body, and slower when it's farther from the central body. If it's in a circular orbit, then its speed is constant. But kinetic energy is 1/2MV2 ... 'M' is mass, and 'V' is speed ... so if the speed doesn't change, then the kinetic energy doesn't change.
A satellite revolves around the earth with uniform speed is the motion of the satellite uniform or accelerated?
Accelerated. The concept of "uniform motion" is a mathematical abstraction, like an infinite plane. ALL mass in the universe is constantly being accelerated by gravitational forces from every other mass in the universe. Specifically, a satellite in orbit is constantly falling toward the Earth under gravity - but because of the inertia of the satellite, it is continually missing the Earth! In the absence of gravity, the satellite would proceed in a straight line tangent to its current elliptical orbit.
How far out from the Earth do you have to be to NOT fall into an orbit?
That would totally depend on your mass.
What constitutes the size of a satellite versus its orbit distance?
There is no relation between the size of a satellite and the size or period of its orbit. Picture an astronaut on a space-walk, floating and hovering six feet from the Space Shuttle. The shuttle's size and mass are both several hundred times the size and mass of the astronaut, but he's in the same earth orbit as the Shuttle is. That's why they stay together. The mathematical relationship ties the satellite's orbital distance to its period ... the time it takes to complete one trip around the orbit. But the satellite's size makes no difference at all; and as long as its mass is nowhere near the mass of the central body, its mass doesn't make any difference either.
An is the path followed by a satellite or celestial body as it goes around a larger mass?
an orbit (usually an ellipse)
How long does it to take to orbit?
That depends on what you are orbiting (specifically, the mass of whatever you want to orbit), and at what distance you want to orbit.
Does the weight of space junk affect its orbital speed?
If something is in orbit it's orbital speed is independent of its mass. Be it a gram or a tonne, it's speed depends only on its orbit; if it had a different speed it would be in a different orbit ( or none at all).
What is the weight of a satellite in orbit?
Technically, a satellite in free-fall (and orbit is a special case of "free-fall") is effectively weightless. What we call weight is the force of the RESISTANCE to gravity; I "weigh" 220 pounds because I an standing on the Earth. The satellite has its own mass, and this can be anything from "tiny" to "enormous".
What is the path of a comet around the sun?
The path of a comet around the sun would depend on its mass, speed, and trajectory. It a comet enters the sun's gravitational field at the correct trajectory and speed, it would fall into a roughly circular orbit.
