Equator - Netflix
Simon Reeve travels to paradise beaches, dense rainforests and towering volcanoes on a 40,000 kilometre journey following the invisible line around the world. For most people, the equator is just an imaginary line around the globe but in this series Simon Reeve comes face-to-face with the reality. On a 40,000-kilometre journey, he reveals the equator as a unique region of our planet; home to both the world's greatest concentration of human poverty and natural biodiversity. Beneath the sweltering heat of the equatorial sun lie paradise beaches, strange foods and exotic wildlife, along with some of the world's most extreme terrains: dense rainforests, towering volcanoes and perilous rapids.

Equator - Celestial equator - Netflix
The celestial equator is the great circle of the imaginary celestial sphere on the same plane as the equator of Earth. This plane of reference bases the equatorial coordinate system. In other words, the celestial equator is an abstract projection of the terrestrial equator into outer space. As a result of the planet's axial tilt, the celestial equator is currently inclined by about 23.44° with respect to the ecliptic (the plane of earth's orbit). An observer standing on Earth's equator visualizes the celestial equator as a semicircle passing through the zenith, the point directly overhead. As the observer moves north (or south), the celestial equator tilts towards the opposite horizon. The celestial equator is defined to be infinitely distant (since it is on the celestial sphere); thus, the ends of the semicircle always intersect the horizon due east and due west, regardless of the observer's position on Earth. (At the poles, the celestial equator coincides with the astronomical horizon.) At all latitudes, the celestial equator is a uniform arc or circle because the observer is only finitely far from the plane of the celestial equator, but infinitely far from the celestial equator itself. Astronomical objects near the celestial equator appear above the horizon from most places on earth, but they culminate (reach the meridian) highest near the equator. The celestial equator currently passes through these constellations: These, by definition, are the most globally visible constellations. Celestial bodies other than Earth also have similarly defined celestial equators.
