What appeared near the Earth in 1986, which hadn't been seen since 1910?
Answer Halley's Comet
Every 75-79 years, Halley's Comet completes its tour of the extended Solar System, returning back to the Earth for a quick pass by. The last time this happened was in 1986, and the next time it will happen will be in 2061. Stay tuned!
