2023年2月16日 · With Pluto spending 20 years of its 248-year orbit within the orbit of Neptune, you might expect that at some point, the two worlds could catastrophically collide. However, Pluto and...

2024年10月30日 · Pluto, with its icy core and nitrogen, methane, and carbon monoxide on its exterior, would break apart by the tremendous gravitational force of Neptune, a gas giant that is 17 times Earth's mass. This fantasy collision would send enormous amounts of ice, gas, and rocky debris into great plumes that would carry remnants into the outer reaches of ...

2005年8月1日 · Pluto and Neptune have resonant orbits. While Pluto makes two revolutions around the Sun, Neptune makes three; so astronomers say Neptune and Pluto are in a 3:2 resonance. This orbital...

Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most- massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume by a small margin, but is less massive than Eris.

Join astrophysicist Neil deGrasse Tyson as he unpacks the stunning news of Pluto's collision with Neptune! In this exciting video, we explore the cosmic implications of this unprecedented event...

Diagrams of the Solar System give the impression that the orbits of Neptune and Pluto cut right across each other, and textbooks even state that Pluto crossed the orbit of Neptune in February 1999. Yet in reality the two planets can never get close to colliding, for two reasons.

2024年11月7日 · The possibility that Pluto may collide with Neptune, one of the most massive gas giants, suggests an event of cosmic proportions which can have an important ramification in the solar system. Potential Collision with Neptune. Obviously, an orbit that makes Pluto and Neptune "alarmingly closer" poses a question of possible collision between the two.

No, Pluto is a so called resonant trans-neptunian object; the orbital period of Pluto is almost exactly 3:2 (1.5) times that of Neptune. This means that every time Pluto nears perihelion and is therefore closest to the Sun and also closest to the orbit of Neptune, Neptune is always at a specific angle (50° according to Wikipedia) in front or ...

2013年2月27日 · From 1979 to 1999, Pluto was the eighth planet from the sun. In 1999, it slipped beyond Neptune to become the ninth. But Pluto's 248-year orbit around the sun takes it 17 degrees above and...

Pluto is usually farthest from the Sun. However, its orbit "crosses" inside of Neptune's orbit for 20 years out of every 248 years. Pluto last crossed inside Neptune's orbit on February 7, 1979, and temporarily became the 8th planet from the Sun. Pluto will cross back over Neptune's orbit again on February 11, 1999 to resume its place as the ...
