The planet Mercury is very difficult to study from the Earth because it is always so close to the Sun. Even at elongation, it is never more than 28 degrees from the Sun in our sky. It is the second smallest planet (it was believed to be the smallest until the discovery that Pluto is actually much smaller than originally thought), and also the fastest in its orbit since it is the innermost planet. In fact, the name Mercury derives from its speed in moving around its orbit.
We began to learn more about Mercury with radar imaging from the Earth in the 1960s, and obtained most of what we know about the planet from the Mariner 10 space probe was placed into a complicated orbit involving Venus and Mercury and which passed close to Mercury and sent back information three times in the period 1974-1976.

Venus is the second planet from the Sun and the sixth largest. Venus' orbit is the most nearly circular of that of any planet, with an eccentricity of less than 1%.Comment

Mars, the "Red Planet", is named after the Roman god of war because it commonly appears with a reddish tinge when viewed in our sky. It has always held a fascination for those interested in the possibility of life on other planets. In 1895 a professor of astronomy, Samual Leland Phelps, wrote in a book called World Making that with a new 40 inch telescope being built by the University of Chicago,
"It will be possible to see cities on Mars, to detect navies in [its] harbors, and the smoke of great manufacturing cities and towns... Is Mars inhabited? There can be little doubt of it ... conditions are all favorable for life, and life, too, of a high order. Is it possible to know this of a certainty? Certainly." (quoted in Feb., 1973 National Geographic)
The adjacent image shows a Viking 2 image of Mars. There is no evidence for the things that Professor Leland thought we would see with an earth-based telescope, but Mars is still of great interest to us, not the least reason being that it may once have harbored conditions favorable to the evolution of life.Comment

Jupiter is the fifth planet from the Sun and by far the largest. Jupiter is more than twice as massive as all the other planets combined (the mass of Jupiter is 318 times that of Earth).Comment
