Kepler's Law implies that a planet inorbit about the Sun moves faster when it is closer to the Sun and slower when it is farther away?
Second
How does the year of a planet closer to the sun compare with one that is farther away?
A planet closer to the Sun has a shorter orbital period, meaning it completes its year in less time compared to a planet that is farther away. This is due to the stronger gravitational pull from the Sun, which causes closer planets to travel faster in their orbits. For example, Mercury, the closest planet, takes about 88 Earth days to orbit the Sun, while Neptune, being much farther away, takes about 165 Earth years. Thus, the distance from the Sun significantly affects the length of a planet's year.
How does the year of a planet closer to the sh compare with one that is farther away why?
A planet closer to the Sun, like Mercury, has a shorter orbital period, meaning it completes a year in less time than a planet farther away, such as Neptune. This difference is due to gravitational forces; the closer a planet is to the Sun, the stronger the gravitational pull, leading to faster orbital speeds. Consequently, planets further from the Sun take longer to complete their orbits due to weaker gravitational attraction and larger distances to cover. Thus, the year length varies significantly based on a planet's distance from the Sun.
Kepler's third law of planetary motion states that planets that are closer to the sun in their orbits?
Actually, Kepler's third law of planetary motion states that the square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit. This means that the farther a planet is from the sun, the longer it takes to complete one orbit.
Does the speed of a planet change during the completion of one orbit?
Yes, the speed of a planet changes during its orbit due to the elliptical shape of the orbit, as described by Kepler's laws of planetary motion. A planet moves faster when it is closer to the Sun (at perihelion) and slower when it is farther away (at aphelion). This variation in speed occurs because of the gravitational pull the Sun exerts on the planet, which is stronger when they are closer together. Overall, the planet's orbital speed is not constant throughout its orbit.
Will a planet or comet be moving faster in its orbit when it is closer to or farther from the sun?
Planets and comets move faster when they are closer to the sun.
Will a planet or comet be moving faster in it orbit when it is farther from or closer to the sun?
Planets and comets move faster when they are closer to the sun.
Kepler's Law implies that a planet inorbit about the Sun moves faster when it is closer to the Sun and slower when it is farther away?
Second
Is the planet Mercury the fastest moving planet in the solar system?
Yes! The closer planets are to the sun the faster they go. Since Murcury is closest, it is the fastest.

How does a planets distance from the sun affect its orbit speed?
Since the gravitational effect of the Sun decreases with distance from it, the planets farther from the Sun do not have to move as rapidly to remain in orbit. (In fact, the speed is what establishes the orbit, not the other way around.) So the outer planets, in addition to having much farther to travel in their orbits, are also moving more slowly. This combination means that outer planets take very much longer to orbit the Sun than do the inner planets such as Earth. By comparison, the length of time it takes (in Earth years) for each of the outer planets to make one complete revolution around the Sun: Jupiter - 11.9 Earth years Saturn - 29.5 Earth years Uranus - 84 Earth years Neptune - 165 Earth years
Which planet is closer to the sun than earth but farther from the sun than mercury?
Mercury is the first planet from the sun, and Earth is the third planet from the sun; Venus is the second planet from the sun, making it farther than Mercury but closer than Earth.
The speed of a planet in its orbit around the Sun depends primarily on the planet's?
The speed of a planet in its orbit around the Sun primarily depends on the planet's distance from the Sun. Planets closer to the Sun move faster in their orbits compared to planets farther away due to the gravitational pull of the Sun. The mass of the planet also plays a minor role in determining its orbital speed.
Earth is closer to the sun in December than in June In which of these two months is earth moving faster around the sun?
Earth moves faster in its orbit around the sun when it is closer to the sun, which happens in December. This is due to the conservation of angular momentum in the solar system, where the closer a planet is to the sun, the faster it moves in its orbit.
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.

How does the speed of a planet depends on its distance from the sun?
This was worked out by Kepler about 400 years ago. Kepler's second law of planetary motion shows how a planet moves faster when it's nearer, in its elliptical orbit, to the Sun. Kepler's third law relates the time a particular planet takes to orbit the Sun to its average distance from the Sun. A planet which is farther from the Sun has a slower orbital speed than a planet closer to the Sun.
