Inner Planets (Greek word wanderer) Mercury - 88 day year. 430 to -170 degrees C. No Atmosphere. No Moons Venus- “Morning and Evening Star”. 480 degrees C. Atmospheric Pressure 92x the Earth’s. Runaway Greenhouse Effect. Day longer than year. Rotates Clockwise; no moons. EARTH –Nitrogen Oxygen Atmosphere. Tilts on Axis at 23 degrees. One moon; Luna. Rotation: 24 Hours, Revolution: 365 Days. Our Moon - Eclipses – When the earth is lined up so as to block the sun’s light from striking the moon it is called a Lunar Eclipse . When the earth is lined up so as to block the moon’s light from striking the sun it is called a Solar Eclipse.

Jupiter - Larger than all the other planets combined. Tremendous magnetic and gravitational fields, has dangerous radiation belts, Rotation of 11 hours, “Red Spot” on surface (hurricane type storm with winds up to 600 mph), 28 moons (Io-volcanoes, Europe and Ganymede-largest moon in solar system, Callisto) Saturn - has a ring system around it, it was a moon of Saturn that was struck by an asteroid and the pieces formed the orbit around Saturn. Density of .71, and water has a density of 1.0, it is the only planet in the solar system that would float in a pool. Rotational speed of about 10 hours; confirmed 18 moons, but evidence of at least 12 more, thus giving Saturn the most moons of any planet; largest moon, Titan, is actually larger than planet mercury.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
