Search for Planets

Formation of the Solar System

Gaia could also play a role in the search for habitable worlds, not by directly detecting terrestrial planets, but by finding systems with a giant planet orbiting far from a solar-type star, a condition that would increase the possibility of finding an inner terrestrial planet harbouring life.

Increasingly more powerful computers will allow numerical simulations of planetary formation and evolution to develop rapidly, providing an invaluable tool for theoretical studies in this field.

Planetary Detection Methods

There are a number of different methods through which planets are being searched for:

  • Dynamical Perturbation of the Star by the Planet

  • Photometry

  • Gravitational Lensing

  • Imaging

You can explore each of these methods by choosing from the content list at the left.
