Well, honey, the object closest to the Earth in all three systems (metric, imperial, and astronomical) is the Earth itself. I mean, who else is gonna be closer to the Earth than the Earth? It's like asking who's the closest to Betty White in sass – it's Betty White, darling.
the moon is the closest to the earth
Venus is the planet that gets closest to the earth, at its closest (inferior conjunction) it is 41 million km from Earth. All of the planets are on different orbits though, so their positions relative to each other are constantly changing - Venus can be nearly to 200 million km away when on the other side of the solar system, further away than the sun. Other inner planets may be the closest to earth at any time, such as Mars or Mercury.
The closest star (aside from the Sun) to Earth is Alpha Centauri. It is about 4.22 light years away from earth. Though we call our star "the sun" its actual name is Sol which is used for the phrase "Solar System". All others are just systems and aren't in any way "solar".
Alpha Centauri is the closest star system to Earth, located about 4.37 light-years away in the constellation of Centaurus. It consists of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. Proxima Centauri is the closest known star to the Sun.
Alpha Centauri is a trinary, about 4.5 light years from earth. Of those three stars, Proxima Centauri is the closest; it is 4.2 light years away.
The Sun is the closest star. Next closest are the three stars of the Alpha Centauri system, of which the closest is Proxima Centauri.
the moon is the closest to the earth
The planet Mercury is closest to the sun, at about three-tenths Earth's distance at the nearest point in its orbit.

The nearest star system to ours is the Alpha Centauri system, located about 4.37 light-years away from Earth. It consists of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. Proxima Centauri is the closest of the three to our solar system.
Polaris is the closest of the three stars.

The Sun is the closest of the three, followed by Neptune, then Andromeda.
The closest star (aside from the Sun) to Earth is Alpha Centauri. It is about 4.22 light years away from earth. Though we call our star "the sun" its actual name is Sol which is used for the phrase "Solar System". All others are just systems and aren't in any way "solar".
The International Astronomical Union (IAU) recognises eight planets in our solar system (from closest to sun to furthest); Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
