- One of the most unlikely animals to be found in the sky is a giraffe. The Greeks called giraffes ‘camel leopards’ because of their long necks and spots, which is where the name Camelopardalis comes from. However, the constellation Camelopardalis was not invented by the Greeks but by the Dutch theologian and astronomer Petrus Plancius in 1612. Plancius first showed it on a celestial globe in that year along with another odd constellation that is still recognized, Monoceros.
- Compass (Wikipedia)
A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with magnetic north. Other methods may be used, including gyroscopes, magnetometers, and GPS receivers.
