What is unique about Pluto’s orbit quizlet?

Space and Astronomy

What is so unusual about Pluto’s orbit? It is more inclined to the ecliptic than any of the eight planets.

What is unique 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.

Is Pluto’s orbit eccentric?

Well, to call Pluto eccentric would be an understatement. With an eccentricity of 0.25 (in other words, ¼ of the way to complete removal from the system), the stretchiness of its orbit is so exaggerated that it spends 20 of its 248-year orbit within the orbit of Neptune.

What is Pluto’s orbit called?

Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune.
Pluto.

Discovery
Eccentricity 0.2488
Orbital period (sidereal) 247.94 years 90,560 d
Orbital period (synodic) 366.73 days
Average orbital speed 4.743 km/s

What is Pluto’s revolution?

Pluto takes 248 Earth years to make one revolution around the sun. That means one year on Pluto is about 248 Earth years. Pluto takes 6 1/2 Earth days/nights to rotate, so one day on Pluto is about 6 1/2 days/nights on Earth.

What are five interesting 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.

Why is Pluto’s orbit inclined?

Pluto’s orbit is also highly inclined. This means that it doesn’t orbit within the same plane as the rest of the Solar System. Instead, Pluto orbits at an angle of 17-degrees. For part of its orbit, Pluto is above the plane of the ecliptic (where the other planets orbit) and other times it’s below that plane.

How else does Pluto’s orbit differ?

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.

How stable is Pluto’s orbit?

Despite this unusual configuration, Pluto’s orbit is remarkably stable due to its 3:2 mean motion resonance with Neptune. This means that for every two orbits that Pluto makes around the Sun, Neptune makes three, which prevents close encounters between them that would otherwise destabilize their orbits.

Why is Pluto different from the other planets?

They are larger than the terrestrial planets, have a larger number of satellites, and no solid surface. Beyond the gas giants, Pluto breaks the pattern by once again showing characteristics more like a terrestrial planet–small, solid surface, and only one (known) satellite.

How is Pluto’s month different?

In short, a single day on Pluto lasts the equivalent of about six and a half Earth days. A year on Pluto, meanwhile, lasts the equivalent of 248 Earth years, or 90,560 Earth days!

How are Pluto and Earth similar?

Bottom line: An analysis of data gathered from New Horizons’ 2015 flyby of Pluto shows evidence of Earth-like snow-capped mountains made of methane ice that bear a striking resemblance to terrestrial alpine landscapes.



How is Pluto similar to the other planets?

Like the planets, Pluto’s spin axis stays pointed in the same direction as it orbits the Sun. But unlike all planets except Uranus, Pluto is tipped on its side. The planets’ axes of rotation stand more or less upright from the plane of their orbits.
