Planet Cards
We used to think there were 9 planets orbiting our sun. A few years ago Pluto was reclassified as a dwarf planet. Subtract 1 from 9 and you have 8 planets orbiting our sun. Currently, there are 5 known dwarf planets that are part of solar system. Science is fun because it is always changing!
The planets in our solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
The dwarf planets are Pluto, Ceres , Makemake, Eris and Haumea.
