Only a few solar system objects are close enough to be explored with probes. . Astronomers rely on electromagnetic waves to gain information about the universe.. "There are countless suns and countless earths all rotating around their suns in exactly the same way as the seven planets of our system. We see only the suns because they are the largest bodies and are luminous, but their planets remain invisible to us because they are smaller and non-luminous. The countless worlds in the universe are no worse and no less inhabited than our Earth”. Science 9. Using scientific notation. Distances in space are very large. We use scientific notation to represent very large and very small numbers. The first digit is between 1 and 9. This is called the base.

So objects in the sky seem to rise in the east & set in the west . North star, Polaris is above North Pole and stars around it seem to form a circle-always present in Northern hemisphere.
