Bright Star

When I read Bright Star I thought it was an odd comparison to make. A star? It kind of has some loopholes in the analogy. I know that Keats is probably righting this poem with very limited knowledge of stars especially considering that this poem was written pre-1821. All of this granted I still am a bit peeved by the lack of correctness and I felt like a blog would be a good place to let it out. First off he says the star is unchangeable but stars actually change a lot throughout the course of their life. He also says the star is steadfast. The star could have actually burnt out millions of years ago and be completely gone. All of this considered I realize that it really has no impact on the poem or its meaning.
