### Earth's perihelion with the Sun

### Earth's perihelion with the Sun

Today, Wednesday, January 4^{th}, 2023, Earth will be as close as it gets to the Sun during its orbit. Shouldn't that make this the warmest time of the year?
In this activity students become familiar with the terms *perihelion* and *aphelion* as they calculate 1 AU and the perihelion distance in miles and kilometers. Students decide how much closer we will be on January 4^{th}, 2023 then at the Earth's aphelion, Thursday, July 6^{th}, 2023, and figure out how long it will take to get to the Sun, leaving now in a school bus, a car, an airplane, a space craft, or in an “n” miles per hour vehicle.

For Adventurer members we have an editable Word docx and solutions/teacher tips.
