Is our solar system only around 20 years old?

>> No.1094386

No it is a few billion years old.

>> No.1094389

Much more recent; it was invented by the IAU in 2006.

If you consider it from the solar systems point of view we have only rotated around the milky way around 20 times.

Fuck what they did to Pluto. I will accept Pluto being downgraded to a dwarf planet when they downgrade Rhode Island to a dwarf state.

The same people who can't seem to name the sun or our moon

>> No.1094441

>>1094430
Because the IAU wants to crush your childhood dreams of pluto

I consider the technical names to be Sol and Luna.

We are the SOLar system, after all. If aliens came to Earth, we would call our sun Sol so that they have a name for it.

They just aren't adopting those names officially because some languages use Sol or Luna for Sun/Moon. At least, that's probably one of the reasons.

That is, of course, if they can pronounce our words or if they can even speak.
