Definitions:
CoronaTop layer of the sun atmosphere that extends from the top of the chromosphere and ranges in temperature from 1 million to 2 million K. Tidal EffectsTides are the rise and fall of sea levels caused by the combined effects of gravitational forces exerted by the Moon, Sun, and rotation of the Earth. Some shorelines experience two nearly equal high and low tides each day, called a semidiurnal tide. Marias a dark region of considerable extent on the surface of the moon Cratera large, bowlshaped cavity in the ground or on the surface of a planet or the moon, typically one caused by an explosion or the impact of a meteorite or other celestial body. RetrogradeA planets backward motion in the sky Rille Valley Like structure that meanders across some regions of the moons maria GalileanAdjective of a relating to galilee Tesserae a small block of stone, tile, glass, or other material used in the construction of a mosaic. Shepherd Satellitesa small moon orbiting close to a planetary ring, especially of Saturn, and whose gravitational field confines the ring within a narrow band. Regoliththe layer of unconsolidated rocky material covering bedrock. FusionProcess in a star’s core in which lightweight hydrogen nuclei combined into heavier helium nuclei Descriptions:
Sun
● Energy created by nuclear fusion
● Coronae are unique to this solar system component
● Its surface temperature is approximately 5800 K
● Produces wind that reaches high speeds near the Earth
● Dark spots are cooler than other regions of its surface
Mercury:
● Size: 1516 mi
● Distance from sun: 35980000 mi
● Planet rotates 1.5 times as it orbits the sun
● Surface looks like that of the Earth’s moon
● Experiences tidal effect created by the sun
● The hottest location on this planet is Caloris Planitia (Caloris Basin)
