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.
In the north, that equinox is called the vernal or spring equinox, the beginning of spring. The other, in September, is the autumnal equinox and is the first day of fall (autumn). In the southern hemisphere, the March equinox is autumnal, and the September equinox is vernal. Around the time of either equinox (which means equal night) the daylight period of the day is about the same length of time as the night time period. Astronomy The term Vernal Equinox has another meaning in astronomy: the point in the heavens which is the location of the Sun at the moment of the northern vernal equinox.
