Why is it difficult to study Pluto?

Why is it difficult to study Pluto?

Pluto is very far from the Sun. In fact it is about 30 to 50 times farther from the Sun than the Earth. So, there is significantly less light from the Sun at the location of Pluto. By the time the light has gone from the Sun to Pluto to Earth, the reflected light intensity is just super small (not a scientific term).

Why don’t we have good pictures of Pluto?

The relative dearth of high-resolution images from Pluto’s far side has frustrated scientists. There are images from New Horizons’ approach to Pluto, they’re just not as high-resolution as the images from the encounter side, since the spacecraft was further away when that side of Pluto was visible.

How do we know what Pluto is made of?

A big clue to a planet’s interior is its average density. Pluto, like many icy worlds, has a density between that of rock and ice – but closer to ice. So that immediately suggests it is a mixture of both. As a planet evolves, heavier materials sink towards its centre.

Did you know facts about Pluto?

Facts about Pluto

• Pluto is named after the Roman god of the underworld.
• Pluto was reclassified from a planet to a dwarf planet in 2006.
• Pluto was discovered on February 18th, 1930 by the Lowell Observatory.
• Pluto has five known moons.
• Pluto is the largest dwarf planet.
• Pluto is one third water.

What is odd about Pluto’s orbit?

It takes 248 Earth years for Pluto to complete one orbit around the Sun. Its orbital path doesn’t lie in the same plane as the eight planets, but is inclined at an angle of 17°. Its orbit is also more oval-shaped, or elliptical, than those of the planets.

Can a telescope see Pluto?

Yes, you can see Pluto but you’ll need a large aperture telescope! Pluto resides at the very edges of our solar system and shines only at a faint magnitude of 14.4. The dwarf planet is 3,670 million miles away from the Sun and looks just like another faint star in your telescope.

What makes Pluto so special?

Aside from being, on average, the farthest planet from the Sun, Pluto and its orbit have several characteristics that make it unique. Its greater distance means its orbital period of 248 years is the longest of all planets. Finally, Pluto itself is unique for its position and physical characteristics.
