Betelgeuse is around 10 times greater in diameter than Rigel.
Rigel: 71 solar radiiAldebaran: 44.2 solar radii.So Rigel is almost twice the size of Aldebaran.See related link for a pictorial of the difference (Section 5).
Oh, dude, Betelgeuse and Rigel are like neighbors in the Orion constellation, they're practically carpooling together! They're only about 860 light-years apart, which in space terms is like being next door. So yeah, they're pretty close in the cosmic neighborhood.
Betelgeuse is a red supergiant star, and as such, it does not have a defined circumference like a solid object. Its size is measured in terms of solar radii, with Betelgeuse being approximately 1,000 times larger than the Sun.
The Earth is slightly larger than Venus in terms of diameter, with Earth's diameter being about 1,200 kilometers larger than Venus'. However, Venus has a similar mass to Earth due to its dense atmosphere.
The Earth is about 3.7 times larger than the Moon in terms of diameter. It is not eight times larger than the Moon.
In terms of size from smallest to largest, its Sirius, Pollux, Aldebaran, Rigel, Betelgeuse, Antares, and KY Cygni.

Venus is slightly smaller than Earth in terms of both mass and diameter.
There is more than one star in the Rigel "system". The main star, in terms of brightness, is Rigel A. That has a surface temperature of about 12,000 degrees Celsius.
Earth is about 53% larger than Mars in terms of diameter.
The Earth is slightly larger than Venus in terms of diameter, with Earth's diameter being about 1,200 kilometers larger than Venus'. However, Venus has a similar mass to Earth due to its dense atmosphere.
No, not even close. In terms of mass, the Sun is about 332,946 times as massive. In terms of volume, the Sun is about 1,300,000 times larger. In terms of diameter, the Sun is about 109 times as wide.
The Earth is about 3.7 times larger than the Moon in terms of diameter. It is not eight times larger than the Moon.
Mars is roughly twice the diameter of the moon.
Mercury's diameter is 0.3825 times that of Earth's
