They are about 4.5 billion years and can range in size from pebbles or lumps of ice, to rocky or icy worlds nearly 1,000...

What is the shape of the universe? Brahe's model of the universe can be explained best with this model below. (p.409, Dictionary of Scientific Biography) In this model, Brahe describes the universe with the earth at the center. The sun orbits the earth while the other planets revolv...

Earths Beyond Earth: The Search for Other Worlds In early 1990, the first extrasolar planet was detected, surprising everyone by its strangeness. More planets have now been discovered outside our solar system than in it. These planets present many great mysteries to the astronomical world. ...

An asteroid is a small or minor planets that are members of the solar system and move in elliptical orbits. Usually found between the orbits of Mars and Jupiter. A comet is relatively small, rocky, and icy. It revolves around the sun. When a comet passes close to the sun some of the ice turns to...

Galileo "Since (as I believe) the opinion of Copernicus that Venus revolves about the sun is correct, it is clear that she would necessarily be seen by us sometimes horned and sometimes not, although the said planet is at equal distances from the Sun, at those times, that is, when the s...

Evaluation of Sidereus Nucius I feel that the motivation of Galileo's pursuits in Astronomy and stargazing was driven by his desire to be financially successful. Galileo was an extremely ambitious and clearly independent individual whose methods of generating scientific data epitomizes a...

Asteroids are objects in outter space that orbit the sun, but aren't quite large enough to be considered planets. Some scientists refer to them as "minor planets" while others call them "planetoids". They are made up of rocky and metallic materials. They come in many shapes, from round to ...
