Transcript of A study on the solar system(ace)97 03
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
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
