Moon Facts: Fun Information About the Earth's Moon How much of it we see depends on the moon's position in relation to Earth and the sun. Though a satellite of Earth, the moon, with a diameter of about 2,159 miles (3,475 kilometers), is bigger than Pluto. (Four other moons in our solar system are even bigger.).The moon is a bit more than one-fourth (27 percent) the size of Earth, a much smaller ratio (1:4) than any other planets and their moons.This means the moon has a great effect on the planet and very possibly is what makes life on Earth possible.oon phases and the moon's orbit are mysteries to many. For example, the moon always shows us the same face. That happens because it takes 27.3 days both to rotate on its axis and to orbit Earth. We see either the full moon, half moon or no moon (new moon) because the moon reflects sunlight.

Pluto Like other Kuiper belt objects, Pluto is primarily made of ice and rock and is relatively small—about one-sixth the mass of the Moon and one-third its volume. It has a moderately eccentric and inclined orbit during which it ranges from 30 to 49 astronomical units or AU (4.4–7.3 billion km) from the Sun.

Makemake: a Dwarf Planet This picture shows how big Makemake is. Compare it to the first three dwarf planets (Pluto, Eris, and Ceres) and to Earth. Makemake is smaller than both Pluto and Eris.It is larger than Ceres. Makemake has a diameter between 1,300 km and 1,900 km. None of the distances between objects in this picture are to scale.akemake is smaller than both Pluto and Eris. Its diameter is between 1,300 and 1,900 km (808 to 1,181 miles). That makes it about three-fourths the size of Pluto. Astronomers haven't found any moons circling Makemake yet.

Why is Pluto not a planet? Pluto is only 0.07 times the mass of the other objects in its orbit. The Earth, in comparison, has 1.7 million times the mass of the other objects in its orbit. Any object that doesn’t meet this 3rd criteria is considered a dwarf planet. And so, Pluto is a dwarf planet. There are still many objects with similar size and mass to Pluto jostling around in its orbit. And until Pluto crashes into many of them and gains mass, it will remain a dwarf planet. Eris suffers from the same problem.

How Big Is Pluto Compared to Earth? Universe Today indicates that Pluto's volume is just 0.59 percent of the Earth's, and that Pluto could fit inside the Earth 170 times. Pluto's surface area is about 3.3 percent that of Earth's, and its mass is just 0.2 percent of the Earth's. Pluto has a much lower gravity than Earth, as well.

What Is Pluto? On average, Pluto is a distance of approximately 39.5 astronomical units, or AU, from the sun. That is almost 40 times farther from the sun than Earth is. Because of its elliptical orbit, Pluto's closest point to the sun is 29.7 AU. This means that Pluto is sometimes closer to the sun than the planet Neptune.n 2006, NASA launched New Horizons, which is the first mission to Pluto. New Horizons is a spacecraft about the size of a piano that is flying to the outer edge of the solar system. The spacecraft will take nine years to reach Pluto. In 2015, New Horizons will spend more than five months studying Pluto and its moons.

Why is Pluto no longer considered a planet? Since its discovery in 1930, Pluto has been a bit of a puzzle: 1  It's smaller than any other planet -- even smaller than Earth 's moon. 2  It's dense and rocky, like the terrestrial planets (Mercury, Venus, Earth and Mars). 3  However, its nearest neighbors are the gaseous Jovian planets (Jupiter, Saturn, Uranus and Neptune).ere's how Resolution 5A defines a planet: Pluto is relatively round and orbits the sun, but it does not meet the criteria because its orbit crosses Neptune's orbit. Critics of the resolution argue that other planets in the solar system, including Earth, have not cleared the neighborhood around their orbits.

Why is Pluto no longer a planet? The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. In August 2006 the International Astronomical Union (IAU) downgraded the status of Pluto to that of dwarf planet..

Meet the Solar System's Dwarf Planets Eris is virtually the same size as Pluto, but it's about 25 percent more massive, suggesting that Eris contains considerably more rock (and less ice) than its Kuiper Belt neighbor. However, the surfaces of the two dwarf planets appear to be similar, composed primarily of nitrogen ice. Like Pluto, Eris has a highly elliptical orbit. But Eris is even more far-flung, orbiting the sun at an average distance of about 6.3 billion miles (10.1 billion km).

What is the distance between Pluto and Earth? Pluto is 4.6 billion miles away from Earth. This number is a bit large, so to make it easier to visualize. The distance between Earth and the Sun is called 1 AU (Astronomical Unit). The distance between Earth and Pluto is 40 AU. It took New Horizons spacecraft nine years to get to Pluto. So yeah, it's pretty far.

- The diameter of Pluto is only 2,390 km across. Just for comparison, that’s about 70% the diameter of the Moon. And it’s a fraction of the size of the Earth; about 18% of the Earth’s diameter. In terms of volume, Pluto only has 6.39 x 10 9 km 3. That sounds like a huge number, but it’s only 0.59% of the volume of the Earth. In other words, you could put almost 170 objects the size of Pluto inside the Earth. The mass of Pluto is 1.3 x 10 22 kg, which is only 0.2% the mass of the Earth, or 18% the mass of the Moon. Needless to say, Pluto doesn’t have very much mass at all. The surface area of Pluto is 1.67 x 10 7 square kilometers. That’s only 3.3% the surface area of Earth, and about the same surface area as Russia. If you could stand on the surface of Pluto, you would experience only 6.7% the gravity you enjoy on Earth.

- It is also the ninth-most-massive known body directly orbiting the Sun, and the largest known body in the Solar System not visited by a spacecraft. It is measured to be 2,326 ± 12 kilometers (1,445.3 ± 7.5 mi) in diameter. Eris is 27% more massive than dwarf planet Pluto, though Pluto is slightly larger by volume. Eris' mass is about 0.27% of the Earth's mass. Eris was discovered in January 2005 by a Palomar Observatory-based team led by Mike Brown, and its identity was verified later that year.

What Is Pluto? Today, Pluto is called a dwarf planet. A dwarf planet is round and orbits the sun just like the eight major planets. But unlike a planet, a dwarf planet does not have enough gravity to attract all of the space dust and tiny objects in its path.A dwarf planet also is much smaller than a planet, but it is not a moon.ost of the other planets orbit the sun in a near-circle with the sun in the center. But Pluto's orbit is an ellipse, and the sun is not in the center. Pluto's orbit is also tilted compared to the orbits of the planets.
