Near miss (safety) A near miss, close call, or nearly a collision is an unplanned event that has the potential to cause, but does not actually result in human injury, environmental or equipment damage, or an interruption to normal operation. A near miss is often an error, with harm prevented by other considerations and circumstances.
An equinox is a period in the orbit of a planet in which the planet's orbit and position cause the Sun to pass directly over the equator. In addition to being an astronomy event of note, it also marks a shift in the seasons.
Equinox literally means equal night, giving the impression that the night and day on the equinox are exactly the same length; 12 hours each. But this isn't entirely true. Equinoxes and solstices happen twice a year. Equinoxes and solstices mark the start of astronomical seasons.
