The Solar System consists of… The Sun Celestial objects bound to it by gravity, such as

planets

Let’s take a look at the 8 planets in our solar system…

Closest planet to the Sun Smallest planet in the Solar System Has no natural satellites(Moons) Temperature = -184°C - 465°C Diameter = 4878km Day(mercury:earth)= 58.6:1

Second closest plant to the Sun Has the highest average temperatures(460°C)

because of : Its proximity to the Sun Its thick atmosphere which contains carbon

dioxide and sulfur dioxide which creates a strong greenhouse effect

Diameter = 12104km Day(venus:earth) = 243:1

Third planet from the Sun The only planet known capable of supporting

life Average temperature on Earth = 7.2°C, but it

varies much more than that at its extremes The hottest temperature ever recorded on Earth

was 70.7°C in Iran. The lowest temperature was -89.2°C in

Antarctica. Diameter = 12756km

Cold Does not have an atmosphere to retain heat Relatively far from the Sun Temperature = approximately -140°C - 20°C Diameter = 6794km Day(mars:earth) = 1:24.6hr

Asteroids are mostly small Solar System bodies composed mainly of refractory rocky and metallic minerals.

Asteroids range in size from hundreds of kilometres across to microscopic

All asteroids save the largest, Ceres, are classified as small Solar System bodies

The asteroid belt contains tens of thousands, possibly millions, of objects over one kilometre in diameter

Despite this, the total mass of the main belt is unlikely to be more than a thousandth of that of the Earth

The main belt is very sparsely populated

Gas Giant Largest Planet Temperature = 21°C Diameter = 142800km Day(jupiter:earth) = 1:9.8hr

Second Largest Planet Temperature = < -175°C Diameter = 273700km Day(saturn:earth) = 1:10.2hr

Axis tilts back 60°! Both poles of planet are illuminated constantly

for 42 years! Dark night lasting next 42 years! 11 rings around itself Diameter = 51800km Day(uranus:earth) = 1:17.2hr

Blanketed by thin clouds and a slender band of rings

Diameter = 49500km Day(neptune:earth) = 1: 16.1hr
