Mercury is the closest planet to the sun. How many days does it take to rotate? 59 days. It goes around the sun in 88 days. You can see Mercury as a dark gray, giant ball of rock. 


Why do you think Venus is the brightest planet? Its yellow clouds contain sulfuric acid, which reflects light from the sun. You can see the planet without binoculars. Venus is the second closest planet to the sun. 


Earth has conditions for animals and humans to live in out of all the planets. Did you know that water covers much of the Earth? Amazing! Also, our planet has one moon.


Have you heard about volcanoes? The biggest volcano in the solar system is on Mars. It’s ‘Olympus Mons’ and is nearly 17 miles tall with a width of 50 miles. 

Ceres (dwarf planet sitting in the asteroid belt)

Scientists discovered a Dwarf Planet and named it Ceres in 1801. It’s located in the asteroid belt between Jupiter and Mars and is the tiniest dwarf planet that astronomers know for now. But Ceres isn’t an actual planet. 


Of all the planets, no planet can beat Jupiter in size because it’s the largest. Its solar system is so huge that you can fit all the planets. Jupiter has the most raging storm in the universe we know.  


The planet follows Jupiter in size; it’s the second biggest. But Saturn is also lighter than all the planets and has multiple rings as thick as 22 planet earths. 


Uranus is one of the furthest planets from the Sun. Like Saturn, it has many rings. 


Earth has 365 days, but a year on Neptune will take 165 years on Earth. Scientists found Neptune in 1846. 


Astronomers now say Pluto is no longer a planet but a planetoid or dwarf planet.  It means we now have eight planets. 

Scientists have also seen dwarf planets beyond Pluto and called them Eris, Haumea, Makemake, and Sedna. Eris came to light in 2015 when astronomers saw an object rotating around the Sun. Eris is the name of a Greek goddess of conflict.

Around 2004 and 2005, astronomers discovered more planetoids and called them Haumea and Makemake. 

Sedna is also another dwarf planet further than the ‘new’ planetoids astronomers have discovered. Its name comes from the Inuit goddess of the Ocean.
