Mars Exploration Milestones
Mars exploration encompasses a series of missions aimed at understanding the Red Planet's geology, climate, potential for past or present life, and suitability for future human colonization. These missions have evolved from early flybys and orbiters to sophisticated landers and rovers, significantly advancing our knowledge of Mars.
Planets
A planet is a celestial body that orbits a star, is massive enough to achieve a nearly round shape through its own gravity, and has cleared its orbital path of other debris. The Solar System comprises eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Beyond our Solar System, thousands of exoplanets have been identified, exhibiting a diverse range of characteristics.
