"4 stars. a good starting book to explore finding Extrasolar Planets. Logically laid out. A joy to read. The average layman should understand it. It is outdated as many new smaller exoplanets have been discovered. We have better instruments now."
"5 stars. The best Mars reference encyclopedia for massive amounts of Mars facts. A huge book,1498. All the information you need about Mars. A must have book for those that have a keen interest of Mars or may develop a life long on/off interest. Great for the life long amateur astronomer."
"5 stars. Great pictures and description of various Martian sites. Past history of Mars. Where the water went and loss of atmoshere and cooling of Mars. also possible landing of Mars. Highly recommended"
