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

• 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.

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.
