Let’s get numerical for a quick second, but keep it chill. On average, Earth is about 93 million miles from the Sun. Mars? Try 142 million miles. That’s a gap of almost 50 million miles—more than half the distance between Earth and the Sun all over again.
Imagine you’re driving a car at 60 miles per hour. To get from Earth’s orbit to Mars’ orbit, you’d need to drive nonstop for nearly 95 years. You’d need a lot of snacks and a very good playlist. That extra distance is why Mars gets so much less sunlight and heat.
Wait, Does Mars Ever Get Close to the Sun?
Here’s where it gets a little tricky, and kind of cool. Mars has a wobbly orbit—it’s more egg-shaped than Earth’s nearly perfect circle. So at its closest point to the Sun (perihelion), Mars is about 128 million miles away. Still, that’s 35 million miles farther out than Earth ever gets.
So even at its sunniest, Mars is still way out in the cold suburbs. It’s like a friend who lives on the edge of town, always saying “I’m just a bit farther down the road.” You never accidentally show up at their house first.
