How can you tell something is a planet and not a moon?
A planet is in direct orbit around a central star, while a moon is in orbit around a large body (a planet) rather than in a direct orbit around a star. The moon orbits the planet, while the planet orbits the sun.
What is the definition of a planet as recognized in astronomy?
A planet is a large naturally occurring spherical body composed of a solid or gaseous surface that orbits and receives radiant energy from a star and that clears away any debris in its orbital path.
What is a body that travels around a star?
A planet is a body that orbits around a star.
How do you define the term 'planet'?
A planet is a celestial body that orbits a star, is spherical in shape, and has cleared its orbit of other debris. In our solar system, there are eight recognized planets, including Earth, Saturn, and Mars.
What is a body that orbits a star is called?
According to the International Astronomical Union, in a 2006 landmark decision, a planet is defined as a i) a celestial body that orbits a star, but is not a star itself; ii) is massive enough to have achieved a nearly spherical shape due to its own gravitational accretion, and iii) has cleared it local neighborhood of significant solar system debris. Under this definition, the classic eight planets are planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune), while other objects are not. For example, Pluto is a dwarf planet, Vesta is an asteroid, and Halley's comet is...a comet.
A relatively large body that orbits a star?
We would call that body a "planet" of the star.
What is a large body of rock or gas that orbits a star?
A large body of rock or gas that orbits a star is called a planet. Planets are celestial objects that revolve around a star like our Sun due to the force of gravity. These celestial bodies can vary in size and composition.

Why isn't Pluto a star?
A star is a celestial body of hot gases that radiates energy from thermonuclear reactions in its interior. Pluto is classified as a dwarf planet, a planet being a large celestial body that orbits a star and does not radiate any large amounts of nuclear energy. The star Pluto orbits in the Solar System is our Sun.
What determines if n object in outer space is a Planet?
A planet is a celestial body which orbits a star, a planet must be large enough for it's own gravity to create it's spherical shape but not too large that it undergoes thermonuclear fusion (thermonuclear fusion is the process of star becoming a star due to it's size) there are many other factors but that was a basic answer.
A planet is a?
A planet is a celestial body that orbits a star, is massive enough for its gravity to shape into a spherical or nearly spherical shape, and has cleared its orbit of other debris or objects. In our solar system, planets like Earth, Mars, and Jupiter orbit the Sun.
A large object that orbits a star is a?
Planet.
What is a body that travels around a star?
A planet is a body that orbits around a star.
How is a planet different from a moon?
A Planet revolves around a central star (our Sun in the case of our Solar System). A Moon revolves around a planet.
A spherical object made of rock or gas that orbits a star?
Such an object is called a planet. We live on the planet Earth.
What determines a planet?
A planet is a celestial body that orbits around a star, is large enough to have its own gravity to form a spherical shape, and has cleared its orbit of other debris. These criteria are set by the International Astronomical Union (IAU) for an object to be classified as a planet.
