Challenge 4- Galaxies and Exo-planets

So in this task we basically had to create an exo-planet system, which was fun...

We had to produce a scale model of the solar system, calculate the 'Goldilocks zone' and decide which planet was most likely to sustain life.

So these are my notes on this challenge:

Goldilocks zone:



sqrt{Lx0.7}=sqrt{1.47}x0.7=0.848704895

sqrt{L}x1.5=sqrt{1.47}x1.5=1.818653348

We found that using this, none of the planets within our given solar system were in the habitable zone.

Habitation:

We found that none of our planets were able to sustain life because:

• They were all gas giants
• None were in the habitable zone
• Carbon concentration may not be high enough for carbon based life forms
• Mass  of all planes was too high as the gravitational force would be too strong
• Luminosity of the star is not bright enough to counteract the distance of the planets
• Planets may not be able to hold an atmosphere due to weak magnetic field
• The mass is big enough that they could attract material like the asteriod belt due to Jupiter.

Mass of planetary objects.

Star: 84g

Planet D: 0.5g

Planet C: 0.5g

Planet B: 0.42g

Distance from star.

Scale: 40cm=80AU 

Planet D: 12cm

Planet C: 19cm

Planet B: 34cm
