* Light-years measure vast distances: A light-year is the distance light travels in one year. It's used for measuring distances between stars and galaxies, not planets within our solar system.
* Earth and Venus are relatively close: The distance between Earth and Venus changes as they orbit the sun, but it's never more than about 261 million kilometers (162 million miles) at their furthest point.
Instead of light-years, we use:
* Astronomical Units (AU): One AU is the average distance between the Earth and the Sun. The distance between Earth and Venus varies but is typically about 0.3 AU.
* Kilometers or Miles: These are more practical units for measuring distances within our solar system.
