Permleton's Lab 7: Mercury

Mercury is the closest planet to the sun. It is called a terrestrial planet because it is mostly made of rock. Since the planet has almost no atmosphere it experiences extreme temperature fluctuations. One really cool things about Mercury is that the surface of the planet is covered in large and small craters from where thousands of meteors have struck the planet. Another strange thing about Mercury is that is year (the time it takes to travel around the sun) is shorter than its day (the time it takes for the planet to rotate around its axis).

Pembleton thinks Mercury is pretty cool! What do you think?


After many nights of studying the stars, Pembleton made an exciting discovery! He discovered a new exo-planet. Pembleton called his friend, Edgar the Elephant to help verify his discovery. Once it was verified, Pembleton decided to reveal his discovery at the Technion Astronomical Society Workshop. He invited Ducky, Ted and Blizzard, along with his friend Edgar the Elephant.

During the lecture Pembleton explained that he was looking for exo-planets by finding shadows that cross in front of bright stars. Pembleton recorded pictures from his Newtonian telescope on to his computer, so that the finding could be verified by other scientist and also for his super cool presentation.

Pembleton’s lecture was a huge hit at the workshop. Now all he has to do is decide on a name for the planet. Maybe it will be… Pembletron… Blizzardonious… Tedzoni… or Duckytopia…What do you think? Leave a comment!
