Pluto has a moderately eccentric and inclined orbit, ranging from 30 to 49 astronomical units (4.5 to 7.3 billion kilometres; 2.8 to 4.6 billion miles) from the Sun. Light from the Sun takes 5.5 hours to reach Pluto at its orbital distance of 39.5 AU (5.91 billion km; 3.67 billion mi).

2024年11月5日 · Pluto’s orbit around the Sun is unusual compared to the planets: it’s both elliptical and tilted. Pluto’s 248-year-long, oval-shaped orbit can take it as far as 49.3 astronomical units (AU) from the Sun, and as close as 30 AU.

2025年1月14日 · Pluto is actually closer to the Sun than Neptune for about 8% of its orbit. Pluto is just one of many icy objects in a distant area of our solar system. Pluto and its large, orbiting moon Charon, are tipped on their sides. Pluto is almost 40 times farther from the Sun than Earth is. All of the above.

2024年1月11日 · Pluto Atmosphere Surface Pressure: ~13 microbar Surface temperature: 24 - 38 K (-247 - -233 C) Scale height: ~18 km lower atmosphere, ~50 km above 30 km Mean molecular weight: ~28 Atmospheric composition: 99% Nitrogen (N 2), 0.5% Methane (CH 4), 0.05% Carbon Monoxide (CO), trace HCN, C 2 H x hydrocarbons

2025年1月19日 · 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.

Pluto's orbit around the Sun is unusual compared to the planets: it's both elliptical and tilted. Pluto's 248-year-long, oval-shaped orbit can take it as far as 49.3 astronomical units (AU) from the Sun, and as close as 30 AU.

Pluto orbits the Sun about 3.6 billion miles (5.8 billion km) away on average, about 40 times as far as Earth, in a region called the Kuiper Belt. A year on Pluto is 248 Earth years. A day on Pluto lasts 153 hours, or about 6 Earth days. Pluto is officially classified as a dwarf planet.

Pluto has a moderately eccentric and inclined orbit, ranging from 30 to 49 astronomical units (4.5 to 7.3 billion kilometres; 2.8 to 4.6 billion miles) from the Sun. Light from the Sun takes 5.5 hours to reach Pluto at its orbital distance of 39.5 AU (5.91 billion km; 3.67 billion mi).

It is the ninth-largest and tenth-massive known object in direct orbit around the Sun. Pluto was reclassified as a dwarf planet in 2006, a move that sparked controversy and disagreement in both the scientific community and the general public.

Pluto is the largest of the Kuiper Belt objects (KBOs) — a collection of ice-rock bodies found beyond the reaches of Neptune’s orbit. We don’t know exactly what created the Kuiper Belt, but the objects within it are thought to be leftovers from the formation of the solar system.
