Hint	Answer	% Correct
It is the densest planet in the Solar System.	Earth	95%
This planet has the larger satellite of the solar system (with a diameter greater than that of the planet Mercury).	Jupiter	85%
This planet has an axial tilt that is almost zero (meaning it has no distinguishable seasons).	Mercury	84%
It is the site of Olympus Mons, the second highest known mountain within the Solar System (the tallest on a planet).	Mars	83%
It has a mass of 317.8 Earths and has the shortest day of all the planets.	Jupiter	77%
It is the only planet of the Solar System that is less dense than water (about 30% less).	Saturn	77%
After the Moon, it's the brightest natural object in the Earth night sky.	Venus	77%
It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System.	Uranus	75%
Is by far the hottest planet in the Solar System.	Venus	71%
Comet Shoemaker–Levy 9 was a comet that broke apart and collided with this planet, providing the first direct observation of an extraterrestrial collision of Solar System objects.	Jupiter	70%
It has two moons, Phobos and Deimos, which are very small and irregularly shaped. Phobos is expected to collide with this planet in the far future.	Mars	70%
A year in this planet is just 88 Earth days long. Also it's the most cratered planet in the Solar System.	Mercury	70%
Its axis of rotation is tilted sideways, nearly into the plane of its revolution about the Sun (meaning that it's rolling around the sun instead of spinning around the sun like the other planets).	Uranus	70%
This planet has a very weak magnetic field. This surprised scientists, who expected it to have a magnetic field similar in strength to Earth's.	Venus	70%
Its largest moon, Titan, is larger than the planet Mercury and is the only moon in the Solar System to retain a substantial atmosphere.	Saturn	69%
This planet revolves around the Sun once every 84 Earth years.	Uranus	69%
The gravitational interaction of this planet with its moon is gradually slowing the planet's rotation and pulling them apart.	Earth	68%
The fifth largest planet in the Solar System.	Earth	68%
The possible presence of underground water oceans on two of its moons has led to speculation that life could be possible there (in Europa and Ganymede).	Jupiter	68%
It is the only planet, other than the Earth, that has polar ice caps.	Mars	68%
Its characteristic surface color is caused by iron oxide, more commonly known as hematite, or rust.	Mars	68%
This planet is 5.5% of Earth's mass and has no moons.	Mercury	68%
Among the gaseous planets in the solar system, it is the most dense.	Neptune	68%
It has a rotation period of 17h 14min and is the coldest planet in the solar system.	Uranus	68%
It is currently host to five functioning spacecrafts (as of 2014).	Mars	67%
It was the first planet found by mathematical prediction rather than by empirical observation.	Neptune	67%
In this planet a day lasts longer than a year (243 versus 224.7 Earth days).	Venus	67%
The atmospheric pressure at the planet's surface is 92 times that of Earth's.	Venus	67%
It has the strongest winds of any planet in the Solar System, with recorded wind speeds as high as 2,100 kilometres per hour (1,300 mph).	Neptune	66%
A persisting hexagonal vortex in the atmosphere around the north pole was first noted in the Voyager images of this planet.	Saturn	66%
This planet has a powerful magnetic field caused by the nickel-iron core of the planet, coupled with its rapid rotation.	Earth	65%
The average distance between this planet and the Sun is over 1.4 billion kilometres (9 times the Sun-Earth distance or 9 Astronomical Units).	Saturn	65%
Its moon, Triton, is the only large moon in the Solar System with a retrograde orbit, which is an orbit in the opposite direction to its planet's rotation.	Neptune	63%
This planet is home to millions of species of life and gradually one of them is extinguishing all the others.	Earth	62%
This planet has the most extreme temperature change between day and night.	Mercury	62%
Even though this planet is called a gas giant, scientists believe it has a solid core.	Saturn	61%
It is the second least dense planet in the Solar System, after Saturn.	Uranus	60%
The gravity on this planet is the second largest of any planet in the Solar System, behind only Jupiter.	Neptune	58%
It is the only planet that has a center of mass with the sun that lies outside the sun itself.	Jupiter	57%
Albert Einstein's General Theory of Relativity finally provided the explanation for the anomalous precession observed on this planet.	Mercury	55%
