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.
- 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.
- 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.
- 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.
- 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.
- Fastest planet.
- Orbits its star from a distance of 740,000 miles.
- One year on the planet haapens every 10 hours.
- Constellation: Sagittarius.
- 22,000 light years from Earth.
- Estimated to be 1650 degrees celsius.

- 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.
