been binging your entire channel
its very good, honestly one of the best channels of this type ive seen
thanks again for watching my stuff, i really appreciate it
You're welcome.
Cool video alfall! Keep up the good work!
Nice video alfallian glad to see you back!
Woah,this is a really goood video,soo why so long you dont post any video .,.?
saran looks like she has a helmet (on your banner or whatever it is called)
The helmet's on the a, but the a is near Saran so I get where you're coming from
@@AlfallMap dont you mean the double p from "Mapping"?
@@AlfallMap also how is slimag a dwarf planet if he isnt in a belt?
@@Reneuser They're classified by size.
@@AlfallMap oh
Where is Kepler 64ab( star ) after red giant
Enveloped by AA
but when is s2 of afotss comming?
Good Video
Good man,
cool
2:54 Excuse me, but why Kepler-64 BA's eyes are like that?
BA's visibly confused
@@AlfallMap ok
What do you mean Alfallian?
nice
I love watching the history of rocks and gas in space
me too. But what do you mean
@@borislavdimitrov8828 He means planets and stars
Rocks meaning rocky planets and gas meaning stars and gas giants
when i hear this im realaxing
How do you get your data?

Star system
The giant planet is Neptune-sized, about 20-55 Earth-masses (MEarth). It has a radius 6.2 times that of Earth. The star system is 7200 light years[10] from Earth.[3][11][6][12] The planet orbits a close binary, with a more distant binary orbiting at a distance, forming the quadruple star system. The star system has the Kepler Input Catalogue name KIC 4862625 as well as the designation Kepler-64. The close binary (Aa+Ab) that the planet circles has an orbital period of 20 days. They form an eclipsing binary pair.[1] The two stars are (Aa) 1.384 solar mass (M☉) F-type main-sequence star and (Ab) 0.336 M☉ red dwarf.[13][3][11][7] The planet orbits this binary pair in a 138.3-day orbit.

The planet PH1b and were used as a benchmark system for automated detection algorithms. As a benchmark system PH1 is used to improve the algorithm and to demonstrate improvement in the detection of circumbinary planets.[15]
