Which planet is the closest in size to Earth?
Venus
Mars
Neptune
Saturn
Venus
Venus is the closest in size to Earth.
The planet closest in size to Earth is Venus. To determine this, we can compare the sizes of the different planets. The easiest way to do this is by comparing their radii (the distance from the center to the outer edge).
First, let's gather the radius measurements for each planet:
- Venus: Approximately 6,052 kilometers
- Mars: Approximately 3,390 kilometers
- Neptune: Approximately 24,764 kilometers
- Saturn: Approximately 58,232 kilometers
Now, we can see that among the given options, Venus has the closest radius to Earth, which is approximately 6,371 kilometers. Therefore, Venus is the planet closest in size to Earth.
