A comet called NEAT not so neatly came close to impacting the sun. This comet was over twice the size of jupiter. A well-timed solarflare blasted it out of its trajectory orbit and so disaster was avoided.
NASA’s SOHO satellite camera caught it all on video. Go here to see the video.
Now, note the large white object entering at the top-right and moving down the screen on the right. This is the NEAT comet. Compare its size to the size of the sun, and you have some idea what it means to say it’s over twice the size of Jupiter. The comet narrowly escaped impact with the sun due to that solar flare–or as the scientists call it, CME (Coronal Mass Ejection).
There are at least a thousand comets that orbit the sun, 160 of those that are near enough to be seen via telescope.
