Equal areas.
Kepler's second law, also known as the law of equal areas, states that a planet sweeps out equal areas in equal times as it moves around the Sun. This means that a planet travels faster when it is closer to the Sun in its orbit and slower when it is farther away.
In our solar system, Jupiter is the planet with the largest radius of 71,492 km It has a mass of 1.8986×1027 kg
Kepler discovered that planets move faster when they are closer to the sun in their elliptical orbits. This relationship is described by Kepler's second law of planetary motion, which states that a planet sweeps out equal areas in equal times as it orbits the sun.
On the new planet, Sara would weigh 400 lbs. This is because weight is proportional to the mass of the planet and inversely proportional to the square of the radius. Since the new planet is 5 times larger in radius, the weight would increase by a factor of 5^2 = 25.
The mass is twice as much, so multiply by 2. The radius is 3 times as much--the gravitational force is inversely proportional to the square of the radius, so multiply by 1/9.2 X 1kg/9 = 0.2 kg.
Yes, the distance from the sun affects the speed of a planet's orbit. According to Kepler's laws of planetary motion, a planet moves faster when it is closer to the sun and slower when it is farther away. This relationship is known as the law of equal areas, which states that a planet sweeps out equal areas in equal times as it orbits the sun.
The circumference of a circle is equal to its diameter times pi. This is also equal to two times its radius times pi.
He thought that the planet went around the sun over 40,000 times faster than in reality. He was a very imaginative person.Really he thought that the closer it was to the sun in its orbit the faster it had to go.
The circumference of a circle with radius 30 is equal to 2 times the radius times pi, or about 188.5.

Kepler's second law, also known as the law of equal areas, states that a planet sweeps out equal areas in equal times as it moves around the Sun. This means that a planet travels faster when it is closer to the Sun in its orbit and slower when it is farther away.

Diameter
According to Kepler's 2nd Law, as a planet moves around its orbit, it sweeps out equal areas in equal times. This means that a planet will move faster when it is closer to the sun (perihelion) and slower when it is farther away (aphelion) to ensure this law is followed.
Because 2 times the radius is equal to the diameter of the circle
the diameter is equal to the radius (*) times two. so, the answer is 10 in.
Kepler's Laws of Planetary Motion:1] Each planet moves in an elliptical orbit with the sun at one focus2] The line form the sun to any planet sweeps out equal areas of space in equal time intervals3] The squares of the times of revolution (days, months or years) of the planets are proportional to the cubes of their average distances from the sun.
