Did you know that the Earth’s moon is the fifth largest body in our solar system? And did you know that Enceladus is the most reflective body in the solar system? And that Saturn is the second largest body in our solar system? These are only a few of the interesting facts you can learn about space.
Earth’s moon is the fifth largest body in the solar system
The moon orbits the planet Earth and is the fifth largest body in our solar system. The moon has a mean radius of 1,737 kilometers, equatorial radius of 1,738 kilometers, and a diameter of 3,474 kilometers. The Earth’s moon is a large body that orbits the planet Earth in a nearly circular orbit. As a result, it appears the same size as the Sun in the sky.
The moons of Saturn and Uranus are the next largest bodies. The dwarf planets in the Kuiper belt are also considered large. Pluto’s giant moon may be as large as Earth. Pluto’s atmosphere is a hundred billion times thinner than Earth’s, and is made mostly of oxygen and hydrogen compounds from vaporized ices.
Enceladus is the most reflective body in the solar system
Enceladus is the sixth largest moon of Saturn and is covered in water ice. The surface of Enceladus reflects almost all of the sun’s light. In fact, the surface of Enceladus is so reflective that it even makes the other moons of Saturn appear brighter. This makes Enceladus the most reflective body in the solar system.
Enceladus is a fascinating and mysterious body in our solar system. It is composed of a large amount of ice and has the highest albedo of any body in our solar system. It was discovered by William Herschel in 1789, and has since been visited by many spacecrafts.
Venus is the second largest body in the solar system
Venus has an atmosphere made mostly of carbon dioxide, nitrogen, and sulphur dioxide. Sulphur dioxide is a greenhouse gas that traps heat from the Sun. This atmosphere results in the planet’s surface temperature being over 465 degrees Celsius (900 degrees Fahrenheit). Venus has a high pressure, 92 times that of Earth. Many things on Venus cannot survive under this high pressure.
Venus rotates very slowly, so that its equator takes 225 days to rotate. The planet’s rotation is anti-clockwise, resulting in its shape. The equator on Venus rotates at 6.52 km/h, compared to the 1,674.4-km-per-second rotation of the Earth. The slow rotation of Venus is one reason why it is often called the “twin” planet of Earth. Venus has slightly less mass and a larger diameter than Earth, but it is still the second largest body in the solar system. The planets also share similar chemical compositions and densities.
Uranus has 27 known moons
Uranus is the most massive planet in the Solar System and is home to 27 known moons. Unlike other planets, Uranus has many moons with names from Shakespeare, Alexander Pope, and other literary sources. The planet’s inner moons are icy and made up of half water, and its outer ring is blue, like Saturn’s E ring.
These moons orbit the gas giant in a circular pattern. Each has a different hemisphere that experiences day and night throughout the year. However, Voyager 2 was only able to observe half of each moon when it flew past the planet during the southern summer. There are also nine irregular moons orbiting the planet on elliptical, inclined, or retrograde orbits. The irregular moons are thought to have formed somewhere else and were captured by Uranus’ gravitational field.
There are more stars in the universe than all the grains of sand on Earth
When we look up into the night sky, we can see stars, but it’s hard to imagine just how many there are. According to Dr. Marshall, there are more stars than the number of grains of sand on Earth. That’s because stars are clustered into vast groups known as galaxies, and the Milky Way galaxy alone contains at least a hundred thousand million stars. And, there are millions, possibly even billions, of other galaxies.
This amazing fact was revealed by astronomers recently. They found that there are ten times more stars in the universe than there are grains of sand on Earth. Scientists estimate that there are about seventy thousand million stars visible from Earth. This is staggering, considering that the Earth’s oceans are filled with trillions of tons of sand.
