What are the criteria that makes a planet a planet?
According to the International Astronomical Union (IAU), a celestial body must meet three criteria to be considered a planet: it must orbit the Sun, it must be spherical in shape due to its own gravity, and it must have cleared its orbit of other debris.
How big does a planet have to be to be a planet?
A planet must meet three criteria to be classified as such: it must orbit the Sun, be nearly round in shape, and have cleared its orbit of other debris. Size alone is not the determining factor in classifying a celestial body as a planet.
How much mass must a planet have to become a star?
For a planet to become a star, it must have enough mass to sustain nuclear fusion in its core. This typically requires a mass of at least 0.08 times the mass of our Sun, known as the hydrogen-burning limit. Below this threshold, the object would be considered a planet rather than a star.
What are two criteria needed for a space object to be considered a planet?
Two criteria for a space object to be considered a planet are: (1) it must orbit the Sun, and (2) it must have enough mass for its gravity to pull it into a roughly spherical shape. Additionally, it must have cleared its orbit of other debris.
Under what circumstances can differentiation occur in a planet?
Differentiation in a planet occurs when the planet's interior heats up and becomes molten, causing heavier materials to sink towards the core while lighter materials rise to the surface. This process can happen during the planet's formation due to gravitational forces.
