10 Interesting Planets Outside Our Solar System

Planets outside the milky way that are different and interesting at the same time.

1. PSR B1620-26 b


  • Artist’s impression of the planet is above in the image.
  • Nicknamed “Methuselah” and “the genesis planet”.
  • Found deep in a “globular cluster” of stars.
  • The oldest exoplanet found to date at 12.7 billion years old.
  • Confirmed in 2003.
  • Constellation: Scorpius.
  • Spectral type: Pulsar/DB.

2. Kepler-10c


  • A mega-earth.
  • Spectral type: G.
  • Constellation: Draco.
  • Discovered in 2011.
  • Completes a orbit around its star in 45.29485 days.
  • The planets oceans represent only 0.02% of our planets mass.
  • 570 light-years from Earth.
  • 17 times heavier then Earth.

3. PSR J1719-1438


  • Diamond planet.
  • Formed from a dead star and a supernova.
  • Orbits a neutron star.
  • The planet is super high pressured.
  • Five times the size of Earth.
  • 4000 light-years away from Earth.
  • Spectral type: Milisecond pulsar.
  • Constellation: Serpens.

4. TrES-4


  • Biggest exoplanet.
  • 1.7 times the size of Jupiter.
  • 1,400 light years away from earth.
  • Orbits around its parent star in only three and a half days.
  • The planet’s large mass to density ration makes it an anomaly among known exoplanets, and its existence cannot be explained by current models.
  • Belongs to a small subclass of “puffy” planets that have very low densities.

5. COROT-exo-3b


  • Densest planet.
  • About the same size as Jupiter, but 20 times the planets mass.
  • Scientists has not ruled out that this planet may be a brown dwarf or a failed star.
  • Constellation: Aquila.
  • It orbits a star called COROT-3.
  • Spectral type: F3V.

6. HD 188753


  • Has three suns.
  • Multiple sunsets like the planet in Star wars called Tatooine.
  • 149 light years away from Earth.
  • It orbits so close to its main star that it goes around it every 3.5 days.
  • Constellation: Cygnus.
  • Spectral type: A: G8V.

7. HAT-P-1


  • The puffiest, a plantnet lighter then a ball of cork.
  • It could float in water if there was a tub to hold it.
  • Discovered in 2006.
  • Calculated temperature: 1322.0 K.
  • 80% as Earh’s gravity.

8. SWEEPS-10

  • Constellation: Sagittarius.
  • 22,000 light years from Earth.
  • Estimated to be 1650 degrees celsius.

9. GJ 1214 b


  • Waterworld with a solid centre
  • 40 light years away from Earth.
  • Atmosphere is filled with steam or blanketed by thick clouds or haze.
  • 2.5 times the size of Earth.
  • 40 light years away from earth.
  • Orbits a red dwarf star.

10. Gilese 581


  • Most habitable and capable to support life.
  • 7 to 17 times the mass of earth.
  • A mega earth.
  • Has harboring oceans, clouds and rainfall, and even more.
  • Has a dense rocky world on the surface.
  • Discovered in 2010.
