No. The equator is tilted about 23.5° from the plane of the Earth's orbit.
No. They orbit in a flat plane in line with Neptune's equator.
No, a satellite in a polar orbit does not remain at the same point over the equator. Instead, it travels over the Earth's poles, allowing it to pass over different points on the equator as the Earth rotates beneath it. This means that the satellite covers a different section of the Earth's surface with each orbit, providing global coverage over time.
Mercury's orbit is inclined at about 7 degrees to the plane of the ecliptic, which is the plane of Earth's orbit around the Sun. This means that Mercury's orbit is tilted relative to Earth's orbit by 7 degrees.
Close, but no. The moon's orbit is inclined to the plane of the Earth's orbit (the ecliptic plane) by about 5.1° . That's the same plane to which the Earth's equator is inclined by about 23.5° degrees ... causing the seasons and all that. If the moon orbited above Earth's equator, then it would always appear the same distance above the horizon as it passed its peak, south of your house (in the northern hemisphere). But you've probably noticed how the moon can appear really high on Winter nights, and really low on Summer nights.
It's because the Earth's axis is tilted. Therefore the plane of the equator is tilted (at about 23.5 degrees) away from the plane of the Earth's orbit. Therefore the celestial equator is tilted away from the ecliptic.
All satellites pass the equator. Twice every orbit.
A satellite in an equatorial orbit flies along the plane of the Earth's equator. If an orbit does not lie at an equatorial orbit, then it will not remain at a fixed state.
I'm not sure what you mean by "a stable orbit". The Earth's center of mass ... nominally the Earth's center ... always lies in the plane of any Earth orbit, so the ground track of the orbit must either cross the equator or coincide with it.
There is no set inclination of a satellites orbit to the earth's equator. Once in space, the spin of the earth or where it's poles happen to be become irrelevant to the satellite. Many satellites like spy and weather satellites orbit over the two poles (north and south) while communication satellites are placed in orbit directly above the equator at a height that is synchronised with the earth's orbit. This way they stay permanently above the same place on the equator and do not APPEAR to move at all.
No. They orbit in a flat plane in line with Neptune's equator.
Mercury's orbit is inclined at about 7 degrees to the plane of the ecliptic, which is the plane of Earth's orbit around the Sun. This means that Mercury's orbit is tilted relative to Earth's orbit by 7 degrees.
Any orbit of the Earth must have its center at the Earth's center. So there are two choices for any Earth satellite: -- Orbit above the equator, never crossing any land that isn't on the equator, and never visible to people who aren't located close to the equator, or else -- revolve in an orbit that's inclined to the equator, sooner or later crossing every point on Earth that lies within the N/S latitudes equal to its inclination, and eventually visible to the majority of Earth's population. A satellite can't, for example, orbit entirely above the Tropic of Cancer, or the Arctic Circle. It must either cross the equator twice in each orbit, or else stay permanently above the equator.
Geostationary satellites.Geostationary satellites.
The planet is Uranus.
In geosynchronous orbit, it's always somewhere over the same meridian of longitude.In geostationary orbit, it's always over the same point on the equator.
All satellites follow an elliptical orbit - they are darn close to circular, but even a circle is an ellipse.
Satellites cannot orbit one country. They may remain in geostationary orbit, but only at the equator. Therefore no satellite stays above only New Zealand.
