Why Could Mars Not Hold Onto Its Atmosphere?

Why could Mars not hold onto its atmosphere? It was too small. … Its atmosphere has excessive amounts of greenhouse gases that warm the planet.

Why can’t Mars hold onto most of its atmosphere?

Earth’s magnetic field protects us from high-energy particles coming from the Sun by deflecting them away from the planet, avoiding our atmosphere from being stripped away. Mars doesn’t have a magnetic field of its own, so solar radiation strikes its atmosphere directly, knocking atoms off into space.
