Halley's Comet
Jacob Jackson
Halley's Comet returns to the part of its orbit visible from Earth.
250,000 years
The Earth magnetic field changes approximately every 200,000 thousand years.
The process of the reversal of the Earth's magnetic poles is called a magnetic flip. This occurs every 4 or 5 times per million years.
science is the pursuit of knowledge. Every science is curiosity based.
No galaxy returns every 76 years. Halley's Comet, which is a comet, not a galaxy, becomes visible every 76 years.
There is no point on the earths surface that experiences night for 24 hours every day.
"Every cloud has a silver lining."
