How cool does this sound? Apparently it only happens about 13 times every 100 years, so you still probably have a pretty good chance of seeing it another time,but according to NASA, it probably won't be for another 30 years. But you can check it out today!
Starting at 7:35 a.m. Eastern Time, it will take a bit more than five hours for Mercury to pass from one side of the sun to the other. As East Coasters, we will be able to see the whole thing! Except... Mercury being the tiniest planet in our solar system will look like just a tiny dot on the sun so using a telescope or watching here might be your best bet!
Like during an eclipse, you will need a solar filter since looking directly at the sun can cause seriously permanent eye damage.
