Earth is closest to the sun at a point called __ a perihelion b precession c apogee d aphelion

## Step 1<br />The question is asking for the term that refers to the point in Earth's orbit where it is closest to the sun. The options provided are: a) perihelion, b) precession, c) apogee, and d) aphelion.<br /><br />## Step 2<br />Let's define each term:<br />- Perihelion: This is the point in the orbit of a planet, asteroid, or comet at which it is closest to its orbital focus, usually the sun.<br />- Precession: This is a change in the orientation of the rotational axis of a rotating body.<br />- Apogee: This is the point in the orbit of the moon or a satellite at which it is furthest from the Earth.<br />- Aphelion: This is the point in the orbit of a planet, asteroid, or comet at which it is furthest from its orbital focus, usually the sun.<br /><br />## Step 3<br />From the definitions, we can see that the term that refers to the point in Earth's orbit where it is closest to the sun is 'perihelion'.
