1.GLIESE 273 b

 

Gliese 283 b orbits the red dwarf star Luyten, located 12 light years away.

- The exoplanet is 84% similar to Earth.

- It has an orbital period of 18.6 days.

- A minimum mass 2 times higher than Earth.

- An average radius 40% higher.

- And an equilibrium temperature of 11 degrees more.

 

2. TEEGARDEN b

 

Teegarden b orbits the red dwarf star Teegarden, 12 light years away.

- The exoplanet is 95% similar to Earth.

- It has an orbital period of 5 days.

- A minimum mass and average radius only 5% higher than Earth.

- And an equilibrium temperature of 9 degrees more.

 

3. GLIESE 1061 c

Gliese 1061 c orbits the red dwarf star Gliese 1061, 12 light years away.

- The exoplanet is 88% similar to Earth.

- It has an orbital period of 6.7 days.

- A minimum mass 75% higher than Earth.

- And an equilibrium temperature of 20 degrees more.

 

4. TAU CETI e

 

Tau Ceti e orbits the solar-type star Tau Ceti, 12 light years away.

- The exoplanet is 74% similar to Earth.

- It has an orbital period of 163 days.

- A minimum mass 3 times higher than Earth.

- An average radius 60% higher.

- And an equilibrium temperature of 30 degrees more.

 

5. PROXIMA B

 

Finally, Proxima b orbits the red dwarf star Proxima Centauri, 4.2 light years away.

- The exoplanet is 87% similar to Earth.

- It has an orbital period of 11 days.

- A minimum mass 30% higher than Earth.

- An average radius 10% higher.

- And an equilibrium temperature of 28 degrees less.

 

To which of these exoplanets would you go to? why?

Honestly, I would pack my bags for TEEGARDEN B because it seems the most earth-like of the planets judging from its temperature and mass, but most likely you would not be able to breathe any of these planet's atmosphere's so any would be fine but that is just my first choice. So given that I would think any of these planets would be fine probably our best bet is PROXIMA B from its closeness to earth. Now to the poster I need to borrow like 3 trillion dollars to make a spaceship that would make it there, can I get a loan?

I have read a lot about exoplanet detection. In my travels I have learned about the star light dimming method (only works if planet orbits in a manner that facilitates being between us and it's star, orbiting like a rotary clock pointer tip faced at us does not work). Also, the wobbling method...detecting tugs on the host star from the shared barycenter changing position (does not work if planet orbit is horizontal to our line of site).

 

Edit: I think I am in error. The wobble detection method should work in all planes in our line of site...still trying to mentally picture it...seems correct.

 

Question, are there any other methods of detection? Or just primarily those two? TX
