Everything is prepared.  You've got your spaceship.  While on journey, suddenly it hits a certain asteroid. Luckily, you are passing through the JAJA System, which consists of a Sun-like star surrounded by seven planets, some of which have moons. Your ship has barely enough fuel and guidance ability to allow you to select a nearby place to crash-land. Below are profiles of each of the planets and moons in the JAJA system. The information is sketchy, but it's all your sensors had time to collect before going off-line due to the damage caused by the Asteroid. Good luck!  Hope you can choose the right Plane 

List of Planets 

Planet A (closest the star) Mass: 1.4 (Earth = 1) Tectonics: Active volcanoes and seismic activity detected. Atmosphere: CO2, N, and H2O Average Temperature: 752 degrees C Description: Thick clouds surround the planet. No surface is visible through the clouds 

Planet B Mass: 0.3 Tectonics: No activity detected. Atmosphere: Thin CO2 atmosphere detected. Average Temperature: 8 degrees C Description: Polar ice caps, dry riverbeds, and many craters can be seen from orbit. 

Planet C Mass: 1 Tectonics: Active volcanoes and seismic activity detected. Atmosphere: CO2, H20 Temperature: 30 degrees C Description: Liquid water oceans cover much of the surface. Volcanic island chains make up most of the dry land. 

Planet D Mass: 1.5 Tectonics: Active volcanoes and seismic activity detected. Atmosphere: N, O2, and ozone layer Average Temperature: 2 degrees C Description: Cold oceans, covered with ice along much of the globe. Some open water around equator. 

Planet E Gas Giant with one large moon. Moon: Sulfur dioxide (SO2) atmosphere. Many volcanoes and hot springs on surface. Temperatures in hot spots can be up to 600 degrees C. Other spots away from volcanic heat can get as low in temperature as 145 degrees C. 

Planet F Gas giant with four large, rocky satellites (moons). Moons have no appreciable atmosphere. Ice detectable on one. 

Planet G (furthest from star) Gas giant with two large moons. Moon 1: Thick methane atmosphere with high enough pressure to keep a potential methane ocean liquid underneath. Temperature: -215 degrees C Moon 2: Covered in water ice. Ice appears cracked and re-frozen in parts, indicating a potential liquid ocean underneath. Surface temperature -100 degrees C. 

Analyze a fictional solar system and select a planet most likely to support life. 

1. Observe the simulation about the planets below. 

2. Choose the possible planet you can land on. 

1. What is the planet of your choice? What makes it habitable? 

2. Comparing the planet of your choice to land in fictional solar system and our planet, do they share the same in characteristics? How do they differ or in what are they similar?  

3. Which is a habitable zone also known as Goldilocks’ Zone? 

4. After finding a possibility of an Earth-like planet in our imagination, let us go back to our solar system and compare our planet to another terrestrial planet that is closer to it in size and distance.
