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.
On Earth, the equinoxes occur around March 21 and September 21, but these dates can vary a day or so either way depending on the cycle of leap years. The US Naval Observatory' â¦ s Earth's Seasons web page can show you the precise time of the equinox each year.
