Why Is Mars Shaped Like a Rugby Ball?

💡 The Answer

• Unlike other rocky planets, Mars is not a perfect sphere — it has different dimensions along all three axes.
• This makes it the only rocky planet in the Solar System with a true triaxial ellipsoid shape.
• Scientists believe ancient massive impacts and internal geological forces caused this irregular form.
• The difference between Mars's longest and shortest axis is significant enough to affect its gravity field.
