Earth's radius is about 6,371 km, so Earth's radius is approximately 1.88 times larger than Mars.
The radius of Earth is about 0.95 times greater than the radius of Venus.
Rigel is a blue supergiant star with a radius about 78 times larger than the Sun. If we assume that Earth's radius is 1/100th of the Sun's radius, then you could fit about 608,400 Earths inside Rigel.
The largest planet in our Solar System is Jupiter. How much larger it is depends on what criterion you use to measure. Its diameter is about 11 times the diameter of Earth. Of course, that means that its radius and circumference are also 11 times as large as the radius and circumference of Earth, respectively. Its surface area is over 100 times larger than that of Earth (just square the diameter ratio), its volume is over a 1000 times larger (proportional to diameter cubed). Jupiter's mass is about 300 times as much as that of Earth. Many planets around other stars have several times the mass of Jupiter, but in many cases, not much is known about their diameter. However, it is expected that a planet that has, for example, 2-3 times the mass of Jupiter will NOT have a much larger diameter, since its stronger gravity will pull it together.
Stars are significantly larger than Earth. For example, the Sun's diameter is about 109 times that of Earth. Larger stars, such as Betelgeuse, can be hundreds or even thousands of times larger than the Sun.
Earth's radius is about 6,371 km, so Earth's radius is approximately 1.88 times larger than Mars.
The sun's radius is about 109 times larger than Earth's radius. Since surface area increases with the square of the radius, the sun's radius is about 11,800 times larger than Earth's surface area.
The radius of the Sun is about 109 times larger than the radius of the Earth.

The radius of Earth is about 0.95 times greater than the radius of Venus.
Jupiter's volume is about 1,321 times greater than that of Earth due to its larger radius. Therefore, Jupiter could accommodate about 1,321 Earths within its volume.

The sun has a radius of approximately 696,340 kilometers, while a star with 0.1 solar radius would have a radius of 69,634 kilometers. To calculate how many times larger the sun is, we divide the sun's radius by the smaller star's radius: 696,340 km / 69,634 km = 10. Therefore, the sun is 10 times larger than a star with 0.1 solar radius.
Two times larger.
Rigel is a blue supergiant star with a radius about 78 times larger than the Sun. If we assume that Earth's radius is 1/100th of the Sun's radius, then you could fit about 608,400 Earths inside Rigel.
Between 10 to 100 times the radius
