29 wrz 2020 · At its most distant point, when Pluto and Earth are on the opposite sides of the Sun from each other, they are separated by about 7.5 billion km / 4.67 billion mi. The closest approach of Pluto to Earth is when the dwarf planet is at only 4.28 billion km / 2.66 billion mi from us.
The temperature on Pluto can be as cold as -375 to -400 degrees Fahrenheit (-226 to -240 degrees Celsius). Pluto's tallest mountains are 6,500 to 9,800 feet (2 to 3 kilometers) in height. The mountains are big blocks of water ice, sometimes with a coating of frozen gases like methane.
The buildup of nitrogen is due to Pluto's vast distance from the Sun. At the equator, temperatures can drop to −240 °C (−400.0 °F; 33.1 K), causing nitrogen to freeze as water would freeze on Earth. The same polar wandering effect seen on Pluto would be observed on Earth were the Antarctic ice sheet several times larger.
16 lip 2024 · Pluto’s mean distance from the Sun, about 5.9 billion km (3.7 billion miles or 39.5 astronomical units), gives it an orbit larger than that of the outermost planet, Neptune. (One astronomical unit [AU] is the average distance from Earth to the Sun—about 150 million km [93 million miles].)
New Horizons discovered huge ridges and mountains of water ice on Pluto, towering up to more than 6 km (nearly 4 miles or 20,000 feet) above the surface. On Earth, a skier heading straight down a 30-degree slope will accelerate to 11 miles per hour in one second if his wax is really good and he's got a good tuck.
On average, Pluto’s temperature is -387°F (-232°C), making it too cold to sustain life. Pluto is orbited by five known moons, the largest of which is Charon. Charon is about half the size of Pluto itself, making it the largest satellite relative to the planet it orbits in our solar system.
