What is the Difference Between Earth and Uranus?

🆚 Go to Comparative Table 🆚

Earth and Uranus are two very different planets in our solar system. Some of the key differences between them include:

  • Size and Composition: Earth is a terrestrial planet, while Uranus is an ice giant. Uranus has a radius of 15,759.2 miles (25,362 kilometers), making it four times wider than Earth. Uranus is primarily composed of elements like hydrogen, helium, water, methane, and ammonia, while Earth is composed of silicate rocks and metals.
  • Position in the Solar System: Earth is the third planet from the Sun, while Uranus is the seventh. Uranus is 19.8 astronomical units (AU) away from the Sun, with one AU being the distance from the Sun to Earth.
  • Moons and Rings: Uranus has 27 moons and 13 rings, while Earth has only one moon.
  • Rotation and Orbit: Uranus rotates on its axis in about 17 hours, while Earth takes 24 hours to complete one rotation. Uranus also has a unique tilt, rotating at a nearly 90-degree angle from the plane of its orbit. One orbit around the Sun takes Uranus 84 Earth years.
  • Atmospheric Temperature: The atmospheric temperature on Uranus is extremely cold, reaching -350°F (-200°C).
  • Magnetic Field: Uranus has a much stronger magnetic field than Earth, with Voyager 2 finding the magnetic field on Uranus to be around 100 times stronger than Earth's.

These differences highlight the distinct characteristics of Earth and Uranus, making them two very unique planets in our solar system.

Comparative Table: Earth vs Uranus

Here is a table comparing the differences between Earth and Uranus:

Specification Earth Uranus
Classification Terrestrial Planet Ice Giant
Diameter 12,742 km 51,118 km
Mass 5.972 x 10^24 kg 8.68 x 10^25 kg
Composition Nitrogen (78%), Oxygen (21%) Hydrogen (83%), Helium (15%), Methane (2%)
Atmosphere Nitrogen, Oxygen, Trace Gases Hydrogen, Helium, Methane
Average Temperature -50°C to 50°C (-58°F to 122°F) -224°C (-371°F)
Atmospheric Color Blue Blue with a slight green tint

Due to their differences in size, composition, and temperature, Earth and Uranus have distinct characteristics and properties. Earth is a terrestrial planet with a breathable atmosphere, a wide range of climates, and the ability to support a diverse range of life forms and ecosystems. On the other hand, Uranus is an ice giant with a cold atmosphere, marked by a constant blue color with a hint of green tint. The two planets share some similarities, including the possession of magnetic fields, atmospheres, and the experience of seasons.
