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.
The year has two equinoxes, which are the days on which the night and day are of equal length. They happen when the apparent position of the Sun (on the ecliptic) crosses â¦ the Earth's equator. The equinoxes are usually March 21 and September 22, and on those days the Sun has a declination of zero and is overhead at the equator.
