It can get pretty cold on Mars - much colder than our own planet, (3) ______________ it’s further away from the sun. At the equator, (4) ______________ can reach 20°C, but at its poles they can drop down to as low as -140°C.
Mars is home to the highest mountain in our Solar System - a volcano called Olympus Mons. Standing a whopping 24 kilometres high, it’s about three times the (5) ______________ of Mount Everest.
You could jump around three times higher on Mars than you can on Earth. This is because the planet’s (6) ______________ - the force that keeps us on the ground - is much weaker.
Mars has two moons. One is called Phobos and the other Deimos.
A day on Mars is 24 hours and 37 minutes - only a little bit (7) ______________ than a day on our own planet. A year on Mars, however, is almost twice as long, lasting 687 Earth days. This is because it takes a lot longer than Earth to complete its (8) ______________ around the Sun.
Until recently, scientists believed that there was no liquid water on the (9) ______________ of Mars - only rocks, soil dust and ice. In 2018, however, they found evidence of a lake under the planet’s south polar ice cap.
Humans have not yet been to Mars, but scientists have sent (10) ______________ there to help them research this fascinating planet. The first spacecraft to land on Mars was the Viking Landers, which touched down on the surface in 1976.
