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.
1 Astronomically speaking, the March equinox occurs when the Sun crosses the celestial equator on its way north along the ecliptic. 2  In the Northern Hemisphere, the March equinox is known as the vernal, or spring, equinox, and marks the start of the spring season.
