Exoplanetary economics refers to the study of economic systems and activities that could arise on planets outside our solar system, known as exoplanets. This field explores how resources, trade, and industries might develop in environments that differ significantly from Earth, considering factors like gravity, atmosphere, and available materials. Researchers in exoplanetary economics analyze potential markets for resources such as minerals, water, and energy that could be harvested from these distant worlds. They also consider the implications of space travel and colonization, including the costs and benefits of establishing human or robotic presence on exoplanets for exploration and exploitation.
