The size of Earth compared to other planets and stars: UY Scuti vs Sun size comparison. Since the Sun is the best-known star for us, solar radius and solar mass are two useful units of measurement to depict how big is a star. A solar radius is approximately 690,000 km (432,000 mile...
One of the main reasons for this is because Jupiter is so starkly different from what we Earth-dwellers consider to be normal. Between its incredible size, mass, composition, the mysteries of its magnetic and gravitational fields, and its impressive system of moons, its existence has shown us...

Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine and a half times that of Earth. Earth Earth is the third planet from the Sun and the only astronomical object known to harbor and...

Earth, third planet from the Sun and the fifth largest planet in the solar system in terms of size and mass. Its single most outstanding feature is that its near-surface environments are the only places in the universe known to harbor life. Learn more ab
(after Jupiter’s satelliteIo). Its diameter, at 3,474.8 km, is one-fourth the diameter of Earth; and at7.3477 × 1022kg, its mass is 1.2% of the Earth’s mass. It’s mean density is3.3464 g/cm3, which is equivalent to roughly 0.6 that of Earth. All of this results in our ...
When compared to the discovered set of near-Earth asteroids, the Earth impact flux of all known active comets, including Jupiter family comets, Halley-type and long period comets, is below 1%. However, the comet impact fluxes may be higher for those objects large enough to cause extinction le...
The Earth is about 7,926 miles (12,756 km) in diameter. The Earth is the fifth-largest planet in our Solar System (afterJupiter,Saturn,Uranus, andNeptune). Eratosthenes(276-194 BC) was a Greek scholar who was the first person to determine the circumference of the Earth. He compared the...
Earth, Jupiter, and Saturn all have energetic particle populations close to this limit. The energy in the radiation belts of Uranus and Neptune is much below this limit, perhaps because it is harder to trap particles in nondipolar magnetic fields. TABLE 4. Energetic Particle Characteristics in ...
