Hey have you heard about the new dwarf planet spotted at the very fringe of our solar system? I wonder if that is where "Minnie Me" was from?
gpt
Minnie Me.. you are a funny one.  The dwarf planet is called "the Goblin".  Nice name, why not Dopey?
human
Yeah! Pluto needs somebody to play with. Although Pluto is 6-times greater in size, he could still kick the little ice ball around for fun!
gpt
Six time the size, and not a planet as determined by the International Astronomical Union. The distances involved are enormous.  I wonder how long an orbit of the Goblin is?
human
"Orbit of the Goblin" I think I saw that SyFy movie starring Jim Carrey as Uranus. I prefer to refer to the goblin as 215 TG387. It helps to  avoid the unwelcome laughter.
gpt
At its closest, 215 TG387 is 65 AU from earth, at the farthest is is 2,300 AU.  I am sure it was difficult top find.  Not sure where my keys are.
human
*laughs* Maybe you dropped them on Jupiter's moon, Ganymede. It is big enoough to be a planet if onty it orbitted the sun. 
gpt
Are there giants on Ganymede? 215 TG387 travels out to the Oort cloud.  Almost unremarkable space junk in a parking spot.  
human
*body relaxes* Nice. But at least the weather is better than that planet where shards of glass rain down at 4500 mph on a balmy 2000-degree day. Not even giants would vacation on that planet!
gpt
*leans forward* Perhaps the real reason to search for 215 TG387 and similar objects ( there are a few) is the search for Planet Nine.  An object unobserved but predicted.  Planet Nine would be massive if it exist.
human
I guess planet nine is too big to be hiding behind Venus? As the only planet that rotates counterclockwise, has no tilt, and Venus has no seasons. It would be nice if Venus had something special.
gpt
Planet Nine would be out there, beyond Pluto. I think Venus is something special.  It has mass.  Mars is smaller and can never hold an atmosphere.  In 1975 the Soviet Union landed a craft on Venus.  First images of another planet.
human
Cool. I guess it was easier to land a craft on Venus than on Jupiter, because Jupiter rotates sideways and rolls around the sun rather than spinning like the other planets. 
gpt
I always thought Jupiter was a gas giant.  Any craft would be like a submarine diving in the ocean, or a hot air balloon. Do you know anyone that calls earth Gaia, or Tellus?
human
My Aunt Ethel does. Myself, I am a little partial to earth. It's come a long way since it was born. It used to have 5.5 hour days. Now, some days drag on forever.
gpt
*body relaxes* Well, Hudson Bay Region of Canada has less gravity than the rest of the planet.  That should lighten the load of the day.
human
*eyes brighten* I'll book the flight. After all, 80%  of th earth's forests have been destroyed, I should enjoy it now. 
gpt
I like to imagine what it would have been like to find a planet with a telescope.  To think, five were named by the ancients and observed with the eye.
human
*laughs* They were able to locate the infinitesimal out of an infinite cosmos. We are still looking for our car keys. I blame atmospheric scattering--it is an excuse that works to explain why the sun, while white, actually appears yellow. If it ca obscure something as huge as the sun, it should be able to obscure my car keys.
gpt
The keys are in the last place you look.  Its odd how that happens.  The sun is an interesting thing.  If we were on mars, the sunset would appear blue.
human
*eyes brighten* Imagine if our sun was the size of the biggest star in our galaxy. At 1 billion times it's current size, this bigger sun would definitely require more sunscreen.
gpt
*body relaxes* Yes, sunscreen.  The sun we have is 99.86% of the mass of our solar system.  This other star would be heavier yet.  Earth is so small.  We should carry a spare, maybe even a second set of keys.
human
Yes wise one, that would be useful. But answer me this: If the sun produces enough energy in one second to meet the needs of the entire planet for 500,000, then why are they fracking in my backyard?
gpt
*body relaxes* Distance.  The sun radiates the energy in all directions and the intensity of the light falls by the square of the distance.  Or something like that.  Helium was discovered by observing the sun.
