The horizon is the apparent curve that separates the surface of a celestial body from its sky when viewed from the perspective of an observer on or near the surface of the relevant body. This curve divides all viewing directions based on whether it intersects the relevant body's surface or not.
horizon, in astronomy, boundary where the sky seems to meet the ground or sea. (In astronomy it is defined as the intersection on the celestial sphere of a plane perpendicular to a plumb line.) The higher the observer, the lower and more distant is his visible horizon. To one 5 feet (1.5 m) above the surface, the horizon is about 2.8 statute ...

The horizon for an average human 1.75 m tall would be about 2.5 km. As the Moon is smaller than Earth, the horizon on our satellite would be closer than Earth's. To compute the distance of the horizon on the Moon, follow these easy steps: Sum the radius of the Moon and your height, and compute the square of the result: (1,737,500 + 1.75)².
The horizon is a visible line that separates all viewing lines depending on whether or not it intersects the Earth's surface. The study of the horizon is called horizon astronomy . The horizon definition in astronomy is defined as, the particular line, which can only be observed when it lies on the sea surface.
Oct 19, 2023 · The astronomical horizon and true horizon are celestial horizons. Earth-Sky Horizons The local horizon, also called the geometrical horizon, is the visible boundary between the Earth and sky. The local horizon may include trees, buildings, and mountains. The geographic horizon is the apparent boundary between the Earth and sky.
Oct 9, 2024 · The horizon is the seeming division between the sky and ground. The horizon can only be observed if viewed from close to the surface of a planet or celestial body. As a human on planet Earth, you’re standing on the Earth’s surface and seeing the curvature of the globe as it meets the sky—that makes the horizon line. [7]

The high-elevation horizon is almost as sharp as the sea-level horizon, but its contrast is less than 10% that of the sea-level horizon. Photographs purporting to show the curvature of the Earth are always suspect because virtually all camera lenses project an image that suffers from barrel distortion.
