  1. Astrobiological Possibilities

  2. Chris Molina Chayson Roberts Jordan Kaun Pablo Alaoan Size and Comparison

  3. Impacts of Life • Planets need to be large enough to support a magnetic field. • High density planets support micro-organism forms of life. (Bacteria) • A planet with water and a atmosphere are more likely to support some form of life. Size plays a major role.

  4. Gravity Comparison to Earth

  5. CHNOPS Justin, Kyoshi, Chris, Derrick

  6. Mars- 96% Carbon, 1.9% Nitrogen, .145% Oxygen, No significant amount of Hydrogen, Minimum amount of Phosphorus, Mercury- 70% Metal, 30% silicate Earth- 20 % Oxygen, .03 Carbon Dioxide, 78% Hydrogen, Less Than1% Other Gases Venus- 96% Carbon Dioxide, 3.5 % Nitrogen Saturn- 96% Nitrogen Jupiter- 90% Nitrogen

  7. Which Planets Are Inhabitable All except for Earth.

  8. Characteristics and Composition Magnetosphere • Created by charged particles, controlled by objects magnetic field • Only “rocky” planets have one • Made up of: • (in order from outer to inner) • -Bow shock • -Magnetosheath • -Magnetopause • -Magnetotail Gary Norman, Erin Northern, Jose Flores, Steven Smith http://www.ck12.org/physical-science/Using-Earths-Magnetic-Field-in-Physical-Science/lesson/Using-Earths-Magnetic-Field/r27/

  9. Magnetospheres of Different Planets • Venus has a magnetosphere that is .09% of Earths • Jupiter has the largest magnetosphere • - 100x larger than Earth • - 7,000,000 kilometers on dayside • Mercury has a magnetosphere that is stronger than Earth’s • Mars has .2% of Earth’s magnetosphere • Saturn has a stronger magnetosphere by 500-1000 times

  10. Magnetosphere of Earth • Heated to 8,000 degrees F • Electrons create vortexes of magnetic energy • Deflects the solar winds (radiation) from the sun, away from Earth’s surface

  11. Orbital Distance

  12. Live EARTH Distance from Sun: 92,960,000 miles (149,600,000 km) Surface Temperature: -88 to 58°C It’s mostly made of Iron, magnesium, sulfur, and nickel. Yes we have liquid water Yes to life. Earth Die Everywhere else Mercury Distance from Sun: 35,980,000 miles (57,910,000 km) Surface Temperature: -173 to 427°C Rocky planet, made up of mainly iron. No liquid water, but they found water Ice. No evidence for life has been found on Mercury. It is unlikely life (as we know it) could survive on this planet.

  13. Die Venus Don’t know what the planet is made of because no spacecraft has survived on the surface. It is 460 degrees F day or night, at the poles or at the equator, it only varies about 3 degree. There is no liquid water. http://www.esa.int/spaceinimages/Images/2005/08/Artist_s_impression_of_the_Venusian_surface Mars It mainly made of iron and sulfur basalt and has iron oxide on the surface to give the planet it characteristic reddish hue. The average temp. is 80 degrees F. Winter near the poles average is 195 degrees F. The equator during the summer average is 70 degrees F, but at night can plummet to 100 degrees F. There is no liquid water, just frozen water. http://news.nationalgeographic.com/news/2014/04/140422-mars-mission-manned-cost-science-space/
