Why is Neptune smaller than Uranus?
Neptune is denser and physically smaller than Uranus because its greater mass causes more gravitational compression of its atmosphere. The planet orbits the Sun once every 164.8 years at an average distance of 30.1 AU (4.5 billion km; 2.8 billion mi).
How much bigger is Neptune compared to Uranus?
Neptune is 17 times the mass of Earth and is slightly more massive than its near-twin Uranus, which is 15 times the mass of Earth and slightly larger than Neptune. It has an equatorial radius of 24,900 kilometers (about 1.4 Earth radii).
How is Uranus different from Neptune?
Uranus and Neptune are the two most distant known major planets in our solar system. Uranus tends to have a blander appearance than Neptune and is mostly cloudless. Neptune’s atmosphere has darker bands than that of Uranus, with streaks and wisps of white clouds, as well as a large “dark spot.”
What planet is bigger than Uranus?
Neptune is slightly smaller than Uranus, but still very large. The planet has a diameter of 49,500 km. You could fit 57.7 Earths inside Neptune, which has a volume of 6.25 x1013 km3.
Which is bigger Venus or Uranus?
If you get the chance to see Venus and Uranus together through a telescope, reflect on the contrast not only in the brightness of these worlds as seen from Earth, but their physical characteristics: Venus is a rocky, terrestrial planet with a dense atmosphere similar in size to the Earth, while Uranus is four times …
How is Uranus similar to other planets?
Its atmosphere is made of hydrogen and helium like Jupiter and Saturn, but it also has methane. The methane makes Uranus blue. Like Venus, Uranus rotates in the opposite direction as most other planets. And unlike any other planet, Uranus rotates on its side.
What is the difference between Uranus and Neptune?
Uranus is larger in diameter than Neptune, while Neptune is more massive than Uranus, but slightly smaller diameter.
How big is Uranus compared to Earth?
Measured at its equator, Uranus is 24,953km to 24,993km, or 3.929 times Earth, while Neptune 24,749km to 24,779km, or 3.883 times Earth. Those numbers are simplified a bit; a Google search will tell you more.
What is the radius of Neptune?
Neptune has the following: Mean radius : 24,622±19 km , Equatorial radius : 24,764±15 km. Polar radius : 24,341±30 km. From perspective of mass : Uranus : 14.536 Earths , Neptune : 17.147 Earths.
What does Uranus look like through a telescope?
In larger amateur telescopes with an objective diameter of between 15 and 23 cm, Uranus appears as a pale cyan disk with distinct limb darkening. With a large telescope of 25 cm or wider, cloud patterns, as well as some of the larger satellites, such as Titania and Oberon, may be visible.
