What are the 4 main criteria used to identify a planet?
A planet is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.
What language did planets come from?

How many types planets are there?
Our solar system contains three types of planets: rocky, terrestrial worlds (Mercury, Venus, Earth, and Mars); gas giants (Jupiter and Saturn); and ice giants (Uranus and Neptune). Planets orbiting distant stars come in an even wider variety, including lava worlds and “hot Jupiters.”
Why are the planets in the order they are?
The order and arrangement of the planets and other bodies in our solar system is due to the way the solar system formed. Nearest to the Sun, only rocky material could withstand the heat when the solar system was young. For this reason, the first four planets – Mercury, Venus, Earth, and Mars – are terrestrial planets.
How do we identify a planet?
The easiest way to pick out planets is to remember this quick rule of thumb: stars twinkle and planets don’t. Seen with the naked eye, planets and stars both appear as pinpoints of light. When you observe a star, you’ll notice that it twinkles and the light may appear to change colors.
Why are the four inner planets called the terrestrial planets?
