SCIENCE SKSU REVIEW

• The three types of chemical bonds are ionic, covalent, and metallic.
• The largest circular storm in our solar system is located on the surface of Jupiter.
• The rapidly moving stream of charged particles that is being driven away from the sun is known as the solar wind.
• The biggest asteroid known is named Ceres.
• Rounded to the nearest day, the Mercurian year is equal to 88 days.
• One of the largest volcanoes in our solar system, if not the largest, is named Olympus Mons and is located on Mars.
• One Jupiter day is equal to 9 hours 50 minutes.
• The time interval between two successive occurrences of a specific type of alignment of a planet (or the moon) with the sun and the earth is referred to as a synodic period.
• The collection of small rocky bodies, otherwise known as minor planets, 99.8 percent of whose orbits lie between the orbits of Mars and Jupiter is known as Asteroids.
• The path in the sky that the sun appears to traverse over the course of a year is known as the ecliptic.
• Refracting telescopes always contain lenses.
• A major component of the interstellar media consists of charged particles which have speeds close to that of light, these particles are known as cosmic rays.
• The term applied to the dark, relatively smooth LUNAR plains whose name is derived from the Latin for "sea" is Mare (singular) or Maria (plural).
• A binary star system lends itself very well to a determination of the total mass of the binary star system.
• A comet's tail points away from the sun.
• I am a type of star with a relatively low effective temperature (3,000 to 4,000 Kelvins), and have a large radius-about 100 times that of the Sun.
• A typical galaxy, such as our Milky Way galaxy, contains approximately 200 billion stars.
• Spectral line splitting due to the influence of magnetic fields is known as Zeeman Effect.
• The total mass of a binary star system can be determined by measuring the separation of the two stars and the stars' period of revolution.
• The Orion Nebula is a good example of an emission nebula.
• Elliptical, Spiral and Irregular are classifications of astronomical systems.
• During the period between 1979 and 1998, Neptune was the farthest planet from the sun.
• The average density of the earth is approximately five and a half times the density of water.
• Newton taught that the natural state of motion of a body is one of uniform motion in a circular path.
• The phenomenon of stars shifting against the background of the more distant fixed stars is referred to as parallax.
• The light-gathering power of a reflecting telescope depends on the area of its objective mirror.
• Galileo was the first individual to observe the phases of Venus.
• The diameter of the earth is approximately 13,000 kilometers.
• Approximately 7.5 times a beam of light could travel around the earth in one second.
• Kepler was the first individual to use Tycho Brahe's observational data on the planet Mars to determine that Mars actually traversed an elliptical orbit, the sun being located at one of the foci.
• The earth's motion around the sun causes relatively nearby stars to shift against the background of the more distant fixed stars.
• The time it takes energy generated in the core of the sun to reach the surface of the sun and be radiated is approximately one million years.
• Retrograde motion is an effect due to the projection of planet orbits onto the sky.
• The series of two-man U.S space missions undertaken in the mid 1960's was named Gemini.
• Venus and Mercury are the only planets that can never be in opposite direction from the Sun in earth's sky.
• Right ascension and declination are the coordinates used for star locations.
• Orion is a constellation.
• Both Saturn and Jupiter rotate faster than the Earth.
• A 5th magnitude star is 15.85 times brighter than an 8th magnitude star.
• Voyager II visited Neptune as its last planet.
