How Do Scientists Gather Data for Comparative Planetology?

Scientists use a variety of methods to gather data for comparative planetology, including:

Space Missions: Robotic missions such as orbiters, landers, and rovers provide detailed observations of planetary surfaces and atmospheres.
Telescopes: Ground-based and space-based telescopes allow for the observation of distant planets and exoplanets.
Spectroscopy: Analyzing the light spectra from planets helps determine their composition and atmospheric properties.
Computer Simulations: Numerical models simulate planetary processes and predict the behavior of planets under different conditions.
