The closest planet to the sun is (D) mercury. An easy way to remember the order of the planets, starting closest to the sun and moving outward through the solar system is to use a memory tool called a mnemonic. A mnemonic is usually a phrase with a pattern of letters or numbers and sometimes that includes poems.
The mnemonic for the planets is MVEMJSUNP which stands for My Very Educated Mother Just Served Us Nine Pizzas or Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto. Although some have changed the N to nachos since Pluto is no longer considered a planet.
