ASTM101 Exoplanet Common Graded Assignment
Create a bar graph to show outer and inner limits of the habitable zone for each spectral class of main sequence stars listed below. Essentially a planet is considered to be in the habitable zone of its star if its distance from its star is between the inner and outer range of the habitable zone. Watch this video to get a sense of what a habitable zone is and isn’t.
Spectral Class Inner (AU)* Outer (AU)*
F 1.1778 3.136
G 0.95 1.676
K 0.392 0.691
M 0.04 0.071
*An AU a unit of distance which is the distance between the Earth and the Sun.
Create a bar graph that shows the range of the habitable zone for each spectral class as listed in the table above. The link for how the graph should be made (with screen shots) is found in the Exoplanet Common Graded Assignment folder in Brightspace. Go to Content, Exoplanet Common Graded Assignment, and then Bar Graph Directions
Paste graph below:
Based on the graph/table above, decide if the exoplanets below would be in the habitable zone or not habitable zone. Make a note IF (and only if) they are VERY close to the inner or outer edge of the habitable zone. Otherwise leave that spot blank.

Part 2:
Go to Class Action, Solar System Characteristics, Animations, Solar System Property Explorer.
Notice in the lower right that you can switch between Radius, Mass, and Density.
Decide if each exoplanet is a sub-Earth (smaller than Earth), super-Earth (larger than Earth), mini-Neptune, or Jupiter like planet by comparing the mass, radius, and density of each exoplanet to the information provided in the Class Action Animation listed above.

Part 3:
Determine which geological eon each exoplanet would be in assuming that life evolved at the same rate as on Earth. Determine what type of life could be present on the planet based on the age of the planet. You must reference at least two sources using MLA or APA.
Note: Be careful of GYA (giga years ago) versus GY (Giga Years). The first system has zero at present times and the second has zero be at the “birth” of the planet. The younger the planet the less complex life should be…

References:
Part 4: Could any of the exoplanets from this assignment be similar to the Earth at present? Refer to your data from parts 1-3 to justify your choice. This discussion can include both which one(s) are similar to Earth and why the others are not.
Part 5: You are in charge of planning the first mission outside of the solar system. Given the travel time to each exoplanet below and the data from Parts 1-3, decide which exoplanet from this assignment to travel to. You must justify your choice. This can include justifying why you wouldn’t send a mission to the other exoplanets. You must cite sources (at least two), both in text and a works cited page, using MLA or APA.
