Space Exit Ticket
| # | Answer |
|---|---|
| 1 | The Milky Way galaxy. |
| 2 | A moon, or natural satellite. |
| 3 | Gravity. |
| 4 | Mercury. |
| 5 | Mars. |
| 6 | A meteor. |
| 7 | The Sun. |
| 8 | A star makes its own light, while a planet reflects light from a star. |
| 9 | An orbit. |
| 10 | Earth rotates on its axis, so different parts face the Sun at different times. |
| 11 | A star and all the objects that orbit it, including planets, moons, and smaller bodies. |
| 12 | Rotation is spinning on an axis; revolution is moving around another object. |
| 13 | Oxygen or nitrogen. |
| 14 | The changing positions of the Moon, Earth, and Sun as the Moon orbits Earth. |
| 15 | The Moon rotates once in the same time it takes to orbit Earth. |
| 16 | An eclipse happens when one space object blocks light from another object. |
| 17 | A lunar eclipse happens when Earth’s shadow falls on the Moon; a solar eclipse happens when the Moon blocks the Sun from Earth. |
| 18 | A group of stars that appears to form a pattern in the sky. |
| 19 | Earth’s rotation makes stars seem to move from east to west. |
| 20 | Earth’s tilted axis as it orbits the Sun. |
| 21 | No. Seasons are mainly caused by Earth’s axis tilt, not by changes in distance. |
| 22 | A telescope. |
| 23 | Comets are icy and can form tails near the Sun; asteroids are mostly rocky or metallic. |
| 24 | A nebula. |
| 25 | Stars form when gravity pulls gas and dust together until the center becomes hot and dense enough for nuclear fusion. |
| 26 | Nuclear fusion. |
| 27 | Mass is the amount of matter in an object; weight depends on gravity, so it changes with location. |
| 28 | The Moon has less gravity than Earth. |
| 29 | The distance light travels in one year. |
| 30 | Space distances are so large that light-years make them easier to describe. |
| 31 | All of space and everything in it, including galaxies, stars, planets, and matter. |
| 32 | The universe is expanding, which is shown by the redshift of distant galaxies. |
| 33 | It means galaxies are moving farther apart over time. |
| 34 | A galaxy contains many stars and solar systems; a solar system has one star and the objects that orbit it. |
| 35 | Planets are closer to Earth and can appear larger and brighter, while stars are very far away points of light. |
| 36 | It moves by pushing exhaust gas backward, which creates an equal and opposite forward force. |
| 37 | Spacesuits provide oxygen, pressure, temperature control, and protection from harmful radiation and tiny particles. |
| 38 | Gravity pulls objects together and can keep moons, planets, and satellites in orbit. |
| 39 | No. The Moon does not make its own light; it reflects sunlight. |
| 40 | It would likely cause major changes in climate and seasons, which could affect plants, animals, and human activity. |
