This is not really a question that can be answered given the wording as it stands. A planet's radius has little or nothing to do with its MASS, which is what 'causes' gravity. For example, Jupiter is far larger than the Earth, but because its' mass is so much less (it's mostly gas, actually) scientists know that Jupiter exerts less gravity than the Earth. And if you had a planet that was smaller than the Earth, but much denser, then you would weigh more there than on the Earth.
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.

Earth is the name for our planet, so it would be exactly the same. The radius of earth is 3,959 miles. The mass is 5.972 × 10^24 kg. The circumference at the equator is 24,902 miles.
Jupiter is the largest planet in the solar system with a 71,492 mile equatorial radius (11.209 times larger than the earth).
There is no single planet named Kepler, rather it is part of the designation given to planets discovered using the Kepler telescope. Most of the planets discovered using the telescope are larger than Earth, but some are smaller.
Venus is a planet that is closest in size to Earth. It has similar bulk composition and gravity to Earth too.
The Earth's radius is6 378.1kmSo that means that the earth is 1.88 (almost 2) times larger.

If a planet has twice the mass of Earth, its radius would need to be larger than Earth's to maintain the same gravitational field strength at its surface. Specifically, to achieve equivalent gravitational acceleration, the radius must increase by a factor of about 1.414 (the square root of 2), not 2. This is because gravitational field strength is directly proportional to mass and inversely proportional to the square of the radius (g = G * M / r²). Therefore, a radius larger by a factor of 2 would actually result in a lower gravitational field strength than that of Earth.
The radius of the Moon's orbit is about 60 times larger than the radius of Earth.
Planet Earth has a radius of about 3,960 miles.
The distance between the Moon and Earth is larger than the Sun's radius. The average distance between the Moon and Earth is about 384,400 km while the Sun's radius is about 696,340 km.
