Mars Strongly Influences Earth's Long-Term Climate

Scientists have discovered that Mars has a much bigger effect on Earth's climate than we thought.

Mars' gravity helps control Earth's tilt and orbit, which affects long-term climate cycles that last hundreds of thousands to millions of years.

These cycles can cause ice ages and other big climate changes.

Before, scientists thought Venus and Jupiter were the main planets affecting these cycles, but now they know Mars plays a big role too.

Mars helps keep Earth's tilt stable and makes some important climate cycles possible.

Without Mars, these cycles wouldn't exist, and Earth's climate would be very different.
