If a dwarf planet were discovered farther from the Sun than Eris, its orbital speed would be slower than that of Eris. According to Kepler's laws of planetary motion, the farther an object is from the Sun, the slower its orbital speed due to the weaker gravitational pull. Thus, this newly discovered dwarf planet would have a longer orbital period and a reduced speed compared to Eris.
The distance of a planet from the sun affects its orbital period. Generally, the farther a planet is from the sun, the longer its orbital period will be. This relationship is described by Kepler's third law of planetary motion, which states that the square of a planet's orbital period is directly proportional to the cube of its average distance from the sun.
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.
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.

According to Kepler's Third Law of Planetary Motion, the square of a planet's orbital period (T) is directly proportional to the cube of the semi-major axis (a) of its orbit. This can be expressed mathematically as ( T^2 \propto a^3 ). Essentially, this means that planets that are farther from the Sun take longer to orbit than those that are closer, with the relationship providing a precise way to compare their orbital periods and distances.

Saturn is slower because it is farther from the sun. The farther away a planet is from the sun, the slower its orbital speed.

Planets that are farther from the sun have longer orbital periods due to the influence of gravity. The gravitational force between the sun and a planet decreases with distance, so planets farther out experience weaker gravitational pulls, resulting in slower orbital speeds. This explains why outer planets like Neptune have longer orbital periods compared to inner planets like Mercury.
The time taken to complete an orbit increases as the distance from the sun increases. 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 directly proportional to the cube of the semi-major axis of its orbit. This means that planets farther from the sun have longer orbital periods.

The planet must be farther from the star than Earth is from the Sun. According to Kepler's third law, a longer orbital period means that the planet must be farther from its star. In fact you could work out its average distance from the star, using Kepler's law.
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.
According to Kepler's Third Law of Planetary Motion, the square of a planet's orbital period (T) is directly proportional to the cube of the semi-major axis (a) of its orbit.

A planet's orbital radius directly affects its orbital period through Kepler's third law of planetary motion. The farther a planet is from the star it orbits, the longer its orbital period will be, assuming all other factors remain constant. This relationship is expressed mathematically as T^2 ∝ r^3, where T is the orbital period and r is the orbital radius.
Use Kepler's Third Law, and compare with Earth's orbit.
