Consider the following observations. classify each observation based on whether it is a real observation (a true statement of something we can actually see from earth) or one that is not real (a statement of something that does not really occur as seen from earth).
- mercury goes through a full cycle of phases
- moon rises in east, sets in west each day
- stars circle daily around north or south celestial pole
- positions of nearby stars shift slightly back and forth each year
- a distance galaxy rises in east, sets in west each day
- we sometimes see a crescent jupiter
- a planet beyond saturn rises in west, sets in east

The real observations are:

Moon rises in east, sets in west each day.

stars circle daily around north or south celestial pole

Positions of nearby stars shift slightly back and forth each year.

A distance galaxy rises in east, sets in west each day.

We sometimes see a crescent Jupiter.

Explanation:

Mercury it can seen from the Earth but no it phases.

Moon is seen in all parts of the Earth, the only difference is that in north pole the stars moves parallel to the horizon.

By the rotation of Earth the relative position of stars changes a little bit.

In the north pole a galaxy can be observed and in the south pole 2 galaxies.

Jupiter is one of the planets that can be seen from Earth in some seasons and it changes the position due to the rotation of planets around the sun.

A planet beyond Saturn is not possible to be observed from Earth just with the naked eye.
