12 - Formation of Planetary Systems Flashcards
What forces produce orbits of planets and moons?
Gravitational Attraction
- Can be Stable orbits or Eccentric orbits
(gravity)
What forces produce regular motion of planets and moons?
Every reaction has an equal or opposite reaction - eg. Earth pulls on Moon, Moon pulls back
Barycentre is a common centre of gravity, position depends on the mass of objects
What is Chaotic Motion?
No fixed orbit - consistently changing, making the motion random
What forces produce ring systems, asteroid belts and internal heating?
What is the Lagrange Point?
What are some of the effects produced when multple bodies interact?
What causes gradual shifts in orbits?
What are the effects of accidental collisions in the Solar System?
What are the main theories for gas giant planets?
What are the current methods for discovering exoplanets?
What are the requirements for life?
What is the possibility of lifeforms existing elsewhere?
What is the relevance of the Goldilocks Zone?
How can factors of the Drake Equation be used to allow us to estimate the number of civilisations in our Galaxy?
