Here's something you don't see every Thanksgiving.
Comet "Ison" will be hurtling toward the sun at 248 miles per second.
This animation shows the comet's projected path.
Ison is expected to sling-shot around the sun tomorrow.
However, NASA isn't sure it will survive.
Ison's tail could get torn off by solar particles, or solar radiation could cook the frozen ice particles and destroy is completely.
NASA says it's taken 5.5 million years for Ison to get here.
If the comet does make it around the sun, it will be easy to see with the naked eye.
