Orbital speed is the speed with which a planet moves around the Sun This speed is determined by?
The mass of the Sun and the distance between the planet and Sun.
As the Sun's mass is (more or less) constant, all we need to know is the distance. Technically this is called the "semi major axis" of the elliptical orbit.
(If you wanted to be really, really accurate the mass of the planet does have a
very very small effect.)

What determines how long it takes a planet to revolve around the sun?
The time it takes for a planet to revolve around the sun is determined by its distance from the sun and its orbital speed. This relationship is described by Kepler's third law of planetary motion, which states that the square of the orbital period of a planet is proportional to the cube of its average distance from the sun.
What Planet Moves Around The Sun In The Shortest Time?
Of the known planets in the solar system, Mercury, being nearest to the sun, completes its orbit in the shortest time . . . 88 earth days.
Is it true that each planet makes one revolution each year?
depends on what you mean. The planets revolve by themselves and around the sun so if you mean just a rotation of a planet then no. If you mean around the sun it depends on how your thinking about it. If you're talking about 365 earth days, then no. Each planet moves at a different speed around the sun and the farther from the sun, the slower the rotation.
What is the path around a planet of a star?
The path around a planet of a star is called an orbit. This orbital path is typically elliptical, with the star at one of the foci of the ellipse, as described by Kepler's laws of planetary motion. The gravitational pull of the star keeps the planet in this orbit, balancing the planet's inertia as it moves through space. The specific characteristics of the orbit, such as its shape and distance from the star, can vary depending on the mass of the star and the planet's velocity.
What describes the speed of a planet traveling in an elliptical orbit around the Sun?
As the planet approaches perihelion (point of nearest approach to the Sun), its orbital velocity gets faster, and it is fastest at perihelion. Similarly, at aphelion (point of furthest approach to the Sun), the orbital velocity is slowest.

Which planet moves the fastest about the sun?
The Sun doesn't move fast, but if you mean which planet moves fast around the sun then it would be Mercury, because it is closer.
Which planet moves the most slowly in its orbit?
Of the major planets, Neptune. The speed of planets in their orbits is directly related to their distance from the sun. The farther a planet is from the Sun, the slower its orbital speed.
What is a large object that moves around a star?
A planet is a large object that moves around a star in a solar system.
What is orbitical velocity?
The planet Mercury has an orbital velocity of 47.8725 kilometers/second. It revolves around the Sun once every 88 days at about 172,332 kph or 107,082 mph.
How does the distance from the sun of a planet affect the planet’s orbitalvelocity?
A planet's orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun's gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun's gravitational pull, and the slower it moves in its orbit.
Which planet moves most slowly around its orbit?
Mercury moves most slowly around its orbit among all the planets in our solar system. It has the shortest orbital period (88 Earth days) and moves at a slower average speed compared to other planets like Venus, Earth, and Mars.

Why are the lenghts of the years on the other planets different?
The length of a planet's year is the time it takes to complete one orbit around the Sun. The closer a planet is to the Sun the shorter its year. There are 2 reasons for that: 1) The planet's orbital path is shorter. 2) The nearer a planet is to the Sun, the faster it moves in its orbit.
How does a planet work?
it moves around the sun
Which outer planet moves around the sun the fastest?
The outer planets are usually defined as Jupiter, Saturn, Uranus and Neptune. The innermost of those, Jupiter, moves around the sun the fastest. The speed of planet is a function the size of its orbit only -- mass doesn't matter, as figured out by Kepler about 500 years ago. Thus Mercury, the innermost of all planets, has the greatest orbital speed (87.96 Earth days for an orbit), and Neptune the slowest (164.81 Earth years). If you want to include Pluto, then it has the greatest orbital period (247.7 earth years)
