Planetfall is a noun that refers to the act of landing or arriving on a planet, typically from an interplanetary journey or space voyage.

It encompasses not only the physical touchdown but also the subsequent establishment of a presence on the planet.
The word "planetfall" signifies the commencement of exploration, colonization, or scientific research on an alien world and can imply a significant milestone for humanity's interaction with extraterrestrial environments. It may involve the deployment of equipment, the disembarkation of crew members, or the deployment of probes and rovers to commence scientific investigations. Additionally, "planetfall" can encompass the excitement, anticipation, and awe that accompanies such a momentous event, epitomizing the pioneering spirit of venturing into the unknown.
Furthermore, beyond its literal meaning, "planetfall" can be metaphorically used to describe any profound arrival or descent to a completely unfamiliar place or environment, whether it be physical or conceptual. It captures the sense of wonderment and novelty experienced when encountering new territory, ideas, or cultures for the first time, underscoring the transformative potential of exploration and discovery.
In summary, planetfall signifies the landing on a planet by a spacecraft or its occupants, implicating the beginning of human interaction with an extraterrestrial environment. Metaphorically, it also expresses the profound arrival or descent to a completely unfamiliar place, reflecting the awe and transformative potential of exploration in both real and metaphorical terms.
The word "planetfall" is a relatively recent term derived from two components: "planet" and "fall".
1. "Planet" is derived from the Greek word "planētēs" which means "wanderer". Ancient astronomers noticed that certain celestial bodies, such as the Sun, Moon, and visible planets, appeared to move differently than the fixed stars. The word "planet" was first used in this context in the English language in the 14th century.
2. "Fall" is derived from the Old English word "feallan" which means "to fall". In this context, "fall" refers to the act of descending or arriving at a specific location.
Combining these two elements, "planetfall" was coined to describe the act of landing or arriving on a planet. It specifically refers to the moment when a spacecraft or other vessel arrives on the surface of a planet after being in space.
