Yes, the planet Mercury is visible from an observer on Earth, without a telescope, although it's harder to spot than Venus. Because its orbit is closer to the sun than ours it will not stray far from the sun in the sky (and unlike planets further out than Earth it will also have phases); it is visible just after sunset or before sunrise depending on the latitude and time of year.
no. the curvature of the earth is what forms the horizon. the horizon is the point where you can no longer see any further because the earth is curving away from your line of sight.
Jupiter is so big that it can be seen from earth with out a telescope
much like it does from earth, only further away.
Yes, if you go out at night you can often see polar satellites. They look like stars moving at a regular speed though the sky, heading either North or South.
Yes, easily. Sirius is the brightest star in the night sky.
very. if you knew where and when to look.
Mars has two natural satellites. Earth has one.
Most communications satellites operate outside of the earth's atmosphere. The GPS satellites are about 23,000 miles from the surface of the earth.
communication satellites, astronomy, navigation, etc.
There are two types of satellites that are located in a foxed spot over earth the first is reconnaissance satellites for observation of earth and usually used by the military.. The second is earth observation satellites and are intended for environmental monitoring
Explain how the remote sensing satellites examined the earth from the space?
light emitted by the satellites
There ias no atmosphere to scatter the sunlight like on earth.
All the satellites, communications, exploratory, military etc. are artificial satellites of Earth.
space satellites are in space and earth satellites are in earth.
Mars has two natural satellites. Earth has one.
Communication satellites orbit around the Earth.Communication satellites orbit around the Earth.Communication satellites orbit around the Earth.Communication satellites orbit around the Earth.
All sorts of things. The Sun, the Moon, planets, asteroids, meteors, galaxies, nebulas, satellites and other things.
Natural satellites are organic objects that orbit the earth such as the moon. Artificial satellites are objects humans propel through the earth's atmosphere in order to orbit the earth such as satellites for TV and radio signals.
what are the names of satellites and robot that have seen neptune.
Satellites of the Earth are held in their orbits by the Earth's gravity. That includes the Moon and all the artificial satellites etc. that are up there.
Why would you classify the moon and earth as satellites?
No. The earth has one natural satellite ... the moon ... and any number of other satellites whose primary purpose is not scientific (e.g. communication satellites).
