What is the difference between the sun and a planet?
The sun is a star emitting energy, light and heat. A planet is a big rock normally orbiting a star.
A planet is a ball of inert material (silica, for example) that receives light and heat from a star. A star is a large ball of gas (primarily hydrogen) that is going through the process of nuclear fusion and producing energy in the process.
The Sun is so massive that planets will almost certainly always revolve around it; the opposite is extremely unlikely.
Along with these structural changes, the Sun will eventually "die" and become an inert, cold, and dense body as helium is burned off from its hydrogen. This is because the Sun's constituent parts that are undergoing thermonuclear fusion are being depleted.

A sun is a star it is significantly larger than a planet and emits energy due to fusion reactions.
A sun or star is a large body consisting of mainly Hydrogen and helium. It is massive enough for fusion reactions to take place in its core. The fusion reactions generate a lot of energy which make a star shine.
A planet is any body which orbits a star and has cleared its orbit of other bodies. A planet can be anything from a small rocky body to a large gas giant.
To put it in perspective the Sun contains over 99.8% of the mass of the solar system.
Some people think Jupiter is a failed star. It is not. It would have to be over 80 times its mass to start any form of fusion reaction.

A planet is a celestial body that orbits a star; unlike stars, planets are smaller and less massive than stars and do not emit light or heat of their own. The sun is a star that produces heat and light as a result of nuclear fusion reactions in its core.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
