Why does a geostationary satellite must orbit around Earth’s equator rather than in some other orbit such as around the poles )? Quizlet?
Solar day is a bit longer because of the Earth’s orbital motion. Why does a geostationary satellite orbit around Earth’s equator rather than in some other orbit (such as around the poles)? … Satellite dishes do not have to track position of a geostationary satellite.
Is the sky part of Earth?
Thanks for the question Saskia. The “sky” actually means everything above the Earth’s surface including space. That’s why so many stars – like our own sun but much further away – light up the night sky. But in between our planet’s surface and outer space there’s the atmosphere.

Where would you have to be on Earth to have the sun at the zenith at noon on June 21?
Solution: On Earth’s equator the celestial equator passes through the zenith. On March 21 the Sun is crossing the celestial equator so it should be found at the zenith (90°) at noon. On June 21 the Sun is 23° N of the celestial equator so it will be 23° away from the zenith at noon.

Why does a geostationary satellite must orbit Earth in 1 sidereal day rather than 1 solar day quizlet?
Briefly explain why a geostationary satellite must orbit Earth in 1 sidereal day rather than 1 solar day. –Satellites orbital period should be one sidereal day. If it was a solar day the satellite would finish the period of rotation a bit late.
Why does a geostationary satellite must orbit around Earth’s equator?
It is always directly over the same place on the Earth’s surface. … Satellites in geostationary orbit rotate with the Earth directly above the equator continuously staying above the same spot. This position allows satellites to observe weather and other phenomena that vary on short timescales.
Why do these satellites must be in geostationary orbit?
Communications satellites are often placed in a geostationary orbit so that Earth-based satellite antennas (located on Earth) do not have to rotate to track them but can be pointed permanently at the position in the sky where the satellites are located.
