Exploration Of Exoplanets

Is It Worth The Risks? What Are The Benefits?

What Are Exoplanets? Facts About Exoplanets.

“Across the sea of space, the stars are other suns.” Said Carl Sagan. But what about the planets that orbit them?


Those planets are called exoplanets, or planets that orbit any other star than our Sun. So here are some facts you may not know about exoplanets.


  1. Most exoplanets are gas giants like Jupiter and Saturn.
  2. Exoplanets such as Kepler22b have a chance of harboring micro bacterial life.
  3. Exoplanets that do not have a star and that are hurtling through space are called Rogue Planets.
  4. Rogue gas giants are called sub-brown dwarfs.
  5. Exoplanets can be detected using The Transit Method and the Doppler Method.
  6. There are exoplanets in almost all know star systems.
  7. Over 2000 exoplanets have been discovered.
  8. Most are detected by the Kepler Telescope.

Is it Dangerous? What Could Happen?

Space exploration can come with many costs. But is it worth it? As you read these, think about the costs. Are they worth if.



  1. A manned mission to nearest exoplanet may prove to be dangerous.
  2. Unknown laws of physics.
  3. Unknown if exoplanets have plate tectonics.
  4. Unknown if life (possibly hostile).
  5. No Atmosphere.
  6. 40 year flight to nearest exoplanet flying at 10% speed of light.
  7. Radiation From space.
  8. Help is 4 light-years away.
  9. All weather predictions will be 40-50 years off.
  10. Unknown if any comets or asteroids will impact exoplanets.


A catastrophe could injure or kill any colonists on an exoplanet. The mission could be jeopardized. It would be another 50 years before a new mission would commence.

How Is It Good? What Can We Gain?

Although there are risks, what are the Benefits? What can come from exploration of exoplanets? Here ten reasons why we can benefit from a mission like this.



  • New Materials.
  • Undiscovered minerals.
  • New area for off-world civilization.
  • New Gasses for fuel.
  • New places to set up telescopes to look even further into space.
  • Able to study new stars (closest are Alpha Centauri A and B).
  • Ability to set up experimental base.
  • Launch probes into deep space.
  • See if life can exist on rogue planets.
  • See how well plant life grows.
