Uranus is the seventh planet from the Sun. … It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. Uranus is similar in composition to Neptune, and both have bulk chemical compositions which differ from that of the larger gas giants Jupiter and Saturn.
What is the fourth largest planet?
Neptune is the fourth largest planet in terms of diameter, making it the smallest in physical size of the gas giants. The average distance from the center of the planet to its surface is 15,299 miles (24,622 kilometers).
Is Earth the 4th largest planet?
While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface. Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal.
Is Uranus 4 times bigger than Earth?
With a radius of 15,759.2 miles (25,362 kilometers), Uranus is 4 times wider than Earth. If Earth was the size of a nickel, Uranus would be about as big as a softball. From an average distance of 1.8 billion miles (2.9 billion kilometers), Uranus is 19.8 astronomical units away from the Sun.
What are the four largest planets made of?
This image shows the four outer planets and the Sun, with sizes to scale. From left to right, the outer planets are Jupiter, Saturn, Uranus, and Neptune. The gas giants are made up primarily of hydrogen and helium, the same elements that make up most of the Sun.
Can u live on Neptune?
Neptune, like the other gas giants in our solar system, doesn’t have much of a solid surface to live on. But the planet’s largest moon, Triton, could make an interesting place to set up a space colony. So far, only a single spacecraft has ever visited Triton.
What is the hottest planet?
Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
What is the fourth smallest planet?
Earth, of course, is the third closest planet to the Sun and the fourth smallest with a radius of 3963 miles (6378 km). Just past Earth is Mars, the fourth planet in the solar system. Mars is the second smallest planet with a radius of 2111 miles (3397 km).
What is the biggest star?
Which planet is bigger Earth or Mars?
Mars (diameter 6790 kilometers) is only slightly more than half the size of Earth (diameter 12750 kilometers). Note the difference in color between the two planets. Almost 70% of Earth’s surface is covered by liquid water. In contrast, Mars now has no liquid water on its surface and is covered with bare rock and dust.
How cold can Uranus get?
speeds on Uranus range from 90 to 360 mph and the planet’s average temperature is a frigid -353 degrees F. The coldest temperature found in Uranus’ lower atmosphere so far is -371 degrees F., which rivals Neptune’s frigid temperatures. Findings from Hubble reveal that clouds circle Uranus at over 300 mph.
Why Uranus is the coldest planet?
It is believed that Uranus exhibits an orbit with a tilt like no other planet. The tilt makes the planet spill out a lot of heat into the space thus retaining very little. Consequently it becomes colder than the other planets.
Where is Uranus right now?
Uranus is currently in the constellation of Aries. The current Right Ascension is 02h 27m 06s and the Declination is +14° 07′ 02”. Uranus is above the horizon from Greenwich, United Kingdom [change]. It is visible looking in the West direction at an altitude of 21° above the horizon.
