∙ 8y agoAn astronomer is a scientist who studies the planets and other astronomical bodies.
Astronomy is the study of the celestial bodies and their compositions, motions, and origins. Most astronomers concentrate on a particular question or area of astronomy, for example, planetary science, solar astronomy, the origin and evolution of stars, or the formation of galaxies. Observational astronomers design and carry out observing programs with a telescope or spacecraft to answer a question or test the predictions of theories. Theorists work with complex computer models of a star's interior, for example, to understand the physical processes responsible for the star's appearance.
Astronomy is different from most sciences in that we can't directly interact with the object of study. That is, it is impossible to dissect, weigh, touch, smell, or otherwise experiment with a star. For the most part, we learn about astronomical objects indirectly by observing the radiation they emit or reflect, and measuring the motions that they and their celestial neighbors exhibit.
(Scientists who study the way cosmic objects interact are called astrophysicists.)
One who studies astronomy - which is basically the study of the Universe, of things which are mainly outside of planet Earth.

What is theDifference between an astrologer and astronomer?
An astrologer looks into the heavens to divine the future. An astronomer looks into the heavens for the science of it.
What is the difference between the astronaut's mass on the earth and on the moon?
There is no difference in an astronaut's mass no matter where he or she might be. Mass is a constant, as opposed to weight which is dependent upon acceleration.None.Put simply. Mass is a measurement of how much matter is in an object, whereas weight is a measurement of how hard gravity is pulling on that object. As their is less gravity on the moon, your weight would be different, your mass would not.
What are the physaical requriments to be a astronmer?
There really are no physical requirements for being an astronomer. An astronomer is a person who studies astronomy, according to Webster's dictionary: "the science of objects and matter beyond the earth's atmosphere." So, physically speaking, any person capable of studdying and learning could become an astronomer. If you are referring to an astronaut, a person who travels into outer space, then there would be a number of other physical requirements.
What is the astronaut salary?
They make between 60,000-140,000
