- 2. Totality may refer to: In astronomy, the state or period of an eclipse when light from the eclipsed body is totally obscured: The coverage of the sun during a solar eclipse.
- 5. An imaginary line around the middle of a planet or other celestial body.It is halfway between the north pole and the south pole,at 0 degrees latitude. An equator the planet into a northern hemisphere and a southern hemisphere Earth is widest at its equator
- 6. that part of a shadow in which all light from a given source is excluded
- 7. the outer part of a conical shadow cast by a celestial body, in which the light from the source is partially blocked
- 9. The point of closest approach to the Earth is known as the perigee (from the Greek peri = near).
- 11. An event in which a planet´s subsolar point passes through its equator.
- 12. tiltAxial tilt,also called obliquity,refers to the angle a planet´s rotation axis makes with the plane of its orbit.The earth is currently tilted 23.5 from this plane,resulting in many remarkable effects,including the seasons around the planet.
- 13. eclipse A lunar eclipse occurs when the Sun, Earth, and Moon align so that the Moon passes into Earth's shadow.
- 14. revolution The rotation of the Earth is the process of it spinning around its axis.The movement of the earth or other planets around the sun. Earth´s rotation causes day and night. Earth´s revolution causes seasons.
- 16. Measure the distance north or south of the equator.Latiude line start at the equator(0 degrees latitude) and run east and west,parallel to the equator.Lines of latitude are measured in degrees north or south of the equator to 90 degrees at the north or south poles.
Down
- 1. Half of spherical or roughly spherical body(such as a planet) specifically: the northern or southern half of the earth as divided by equator(see equator sense 2) or the eastern or western half as divided by a meridian(see meridian sense 1a)
- 3. eclipse The Sun is never completely blocked by the Moon during an annular solar eclipse
- 4. The point in the orbit of an object(such as satellite) orbiting the earth that is at the greatest distance from the center of the earth.
- 7. An orbit's closest point to the Sun
- 8. point in the orbit of a planet, comet, or other body most distant from the Sun.
- 10. The point where the Sun appears to reach either its highest or lowest point in the sky for the year.
- 14. rotation Earth takes 24 hours to complete one spin,and mars takes 25 hours.The gas giants rotate really fast. Jupiter takes justo 10 hours to complete one rotation. Saturn takes 11 hours, Uranus takes 17hours, and Neptune takes 16 hours.
- 15. eclipse happens when the Moon passes between the Sun and Earth, casting a shadow on Earth that either fully or partially blocks the Sun's light in some areas
