Sue, I don’t have this in my library and am not familiar with it. Some suggestions for other books might be:
Galileo – many bios out there
King’s Astronomer by Deborah Crawford – story of William Hershal, discoverer of Uranus
Dear Rebecca, Winter is Here by Jean Cragihead George – good book that explains winter solstice
Bios on Copernicus, Kepler, Benjamin Banneker, Maria Mitchell, Newton,
Many books on astronomy experiments such as those by Janice VanCleave
Also books on invididual topics such as solar system, galaxies, nebulae, etc.
Not sure if that helps. I can look up specific titles if you need them
