If Celestia could send Nightmare Moon to the moon, could Luna send a 조랑말 to the sun?

If she wanted to be sisterless.. Maybe

Eeyup,they're like the supreme rulers of Equestria and stuff..so yeah..you know its kinda like the Fim Fiction "Past Sins" when in the s1 ep1 Celestia Disappeared and Nightmare was now there,in the fanfic it said that maybe Luna banished her to the sun after she escaped the moon and then >> elements of harmony >> NMM defeated and back to normal >> Celestia suddenly appearing from the sky? (in fanfic: 또는 when Nyx trapped them inside the sun and the moon respectively)

Maybe not the sun, but I think she could also send ponies to the moon.

I'm sure she could because otherwise that would be unjust. Besides even if she could why would she do that?

Interesting theory. But if she could, why didn't she do it when she was Nightmare Moon? 'Cause I know she'd want to as Nightmare Moon.

That would make for an amusing creepypasta.
