Apostrophe

In "Bright Star" by John Keats, an apostrophe is present throughout the poem. The speaker is addressing the personified star. This is more effective than just describing the star because it makes it easier to visualize the star. I can put myself in that situation. I could go outside and speak to a star if I wanted, and I would have more insight than just staring at it. It allows you to picture yourself as the star. I can see myself looking down at the world and seeing the sun in space. This provides a softer tone for the poem.
