Earth observation satellites are satellites specifically designed to observe Earth from orbit, similar to spy satellites but intended for non-military uses such as environmental monitoring, meteorology, map making etc.
orbit
If the satellite is in an orbit that takes it over the North and South Poles, it will eventually cover all parts of the Earth as the Earth spins beneath it. This kind of orbit is called a polar orbit.

The Sun,Earth's orbit, the oceans,greenhouse gases,and dust.
The worlds' first artificial satelite was put in orbit by Soviet Union in 1957, named Sputnik 1. Since then thousands of prolab satelites were put in orbit by several countries around the globe.
Solid objects that can orbit planets are called moons. Moons are natural satellites that orbit around planets in a similar way that planets orbit around stars. Moons can range in size from small rocky bodies to larger worlds with their own atmospheres.
The Earth's tilt and orbit cause seasonal temperature changes.
The axis is actually an imaginary line that the Earth spins around. It represents the tilt of the Earth relative to its orbit.
An elliptical orbit would increase the temperature variation of the planet in general. it wouldn't do anything to either season specifically. Remember, when it's summer in the northern hemisphere, it's winter in the southern.
When Earth's orbit elongates due to factors like orbital eccentricity, temperatures can fluctuate but not solely due to this factor. Other factors such as solar radiation, greenhouse gas levels, and volcanic activity play a significant role in determining global temperatures.
Earth
Tidal forces between the Sun and the Earth cause friction in Earth's surface - sort of a rippling - that slows the orbit. It is easier to see these tidal forces acting on the water in our oceans than it is to see in our land, but they are there.
