In astronomy, egress is another word for emersion, the emergence or exit of a heavenly body from an eclipse, occultation, or transit-that is, when it comes back into view. A parking lot might have some one-way access points devoted to ingress and others devoted to egress.

For example, a fire safety code often requires a building to have multiple points of egress-places for people to exit, such as doors and fire escapes.
What does egress mean?Įgress means “the act of going out,” “the right to go out,” or “the means of going out.” The last sense is the one used in relation to architecture and related fields. In astronomy, ingress is another word for immersion, the entrance of a heavenly body (such as a planet or a moon) into an eclipse caused by another heavenly body (like when the moon moves into Earth’s shadow) or into another instance of their paths crossing in some way (such as an occultation or a transit). The word isn’t always used in relation to buildings-it could be applied to parking lots, for example, which often have multiple points of ingress for vehicles to enter. It’s a concise way of referring to a place where people can enter that avoids using a more specific term, like door (since points of ingress might not all technically be doors). A point of ingress in a building is an entryway. Ingress means “the act of entering,” “the right of entering,” or “the means of entering.” The last sense is typically the one used in relation to architecture and related fields. In astronomy, they’re used in a more specific way relating to heavenly bodies (like planets) entering into or emerging from an eclipse. Egress refers to both the act of exiting or to an exit itself.
Ingress can refer to both the act of entering or to an entryway (an entrance) itself. Join us as we get into the ins and outs of ingress and egress. But there’s a lot more to know about these words and how exactly they’re used-including in astronomy and in terms like egress window. You can probably guess from the in in ingress that it generally means “the act of going in” or refers to an entryway. They’re primarily used in the context of entrances and exits, especially in architecture and other fields related to planning how people get in and out of places. Ingress and egress look and sound like they’re opposites, and they are.
