A dwarf planet is a?

1.small, rocky object that orbits the Sun and is usually found in a belt between the orbits of Mars and Jupiter.
2.small object made of ice and dust that orbits the Sun and forms a coma as it approaches the Sun.
3.round object that orbits the Sun but lacks the ability to clear the neighborhood around its orbit.
4.meteoroid that burns up in Earth’s atmosphere, producing a streak of light.

Respuesta :

Answer:

3.round object that orbits the Sun but lacks the ability to clear the neighborhood around its orbit.

Explanation:

in 2006 the IAU, said that a dwarf planet is round object that has not cleared the area round a object and that is why Pluto, Ceres, and Eris are dwarf planet.

Answer:

A dwarf planet is a "round object that orbits the Sun but lacks the ability to clear the neighborhood around its orbit." (option 3)

Explanation:

A dwarf planet is defined as a celestial body that is characterized by:

  • Being in orbit around the Sun (rotate around this)
  • Its mass is enough for its own gravity to exceed the stiff body strength. In other words: it has a spherical or almost spherical shape determined by hydrostatic equilibrium.
  • It is not a planet's satellite.
  • It has failed to clean the neighborhoods of its orbit. In general, a star reaches a certain level of evolution and incisively influences the surrounding stars, either by attracting them, moving them away or making them revolve around it. This is not the case with dwarf planets, which causes other relatively independent stars to exist around their orbit. In other words, the planet revolves around the Sun accompanied by other celestial bodies that perform the same orbit (it is not gravitationally dominant as it shares its orbital space with other bodies of similar size).

In summary, a dwarf planet is a "round object that orbits the Sun but lacks the ability to clear the neighborhood around its orbit." (option 3)
