Name: Date: Period: 1. are natural or artificial bodies that revolve around more massive bodies such as planets. (Satellites or Comets) 2. Most lunar craters are the result of . (volcanoes or impacts) 3. The time it takes for Earth to around the sun is 1 year.
What is Earth’s place in the solar system? 6. How close are the nearest stars to the Sun as compared to the distance between the Sun and the Earth? 7. How large is the Milky Way galaxy?
2. Temperatures in the corona can reach over 1 000 000 ̊C. 3. It is the thickest layer, stretching several million kilometres into space. Phenomena on the Sun’s surface | 1.
(1) The orbit of each planet is an ellipse with the Sun at one focus. (2) As a planet moves around its orbit, it sweeps out equal areas in equal times. (3) More distant planets orbit the Sun at slower average speeds, obeying the mathematical relationship p2 = a3. h. How does the Earth rotate and how does that relate to day and night or the seasons? The Earth rotates on its axis and orbits the Sun.
Jupiter is the largest planet in the solar system, the 5th from the Sun. It is not quite as bright as Venus when seen from Earth. Measured across, Jupiter is ten times the size of the Earth and one-tenth the size of the Sun. Like the Sun and Saturn, it is mostly hydrogen and helium. There may be a small core of rock and perhaps ice at the center.

Cepheid variable stars have masses much larger than our Sun; the more massive stars are more luminous and have more extended envelopes 10. The stars near the centers of galaxies are orbiting at high velocities, which mean that there is the presence of super-massive black holes in the centers of most galaxies. 11. Large galaxies can absorb smaller galaxies called galactic cannibalism. Chapter 14 1.
Chapter 1 • Review the components of our solar system – sun, planets, moons, asteroids, comets and their definitions o Star – a large, glowing ball of gas that generates heat and light through nuclear fusion o Planet – a moderately large object that orbits a star; it shines by reflected light. Planets may be rocky, icy, or gaseous in composition o Moon (Satellite) – an object that orbits a planet o Asteroid – a relatively small and rocky object that orbits a star o Comet – a relatively small and icy object that orbits a star o Solar System – a star and all the material that orbits it, including its planets and their moons o Nebula – an interstellar cloud of gas and/or dust o Galaxy – a great island of stars in space, all held together

Comet tails are made up of simple ionized molecules, including carbon monoxide and dioxide. By action of solar wind, molecules are blown away, forming a thin stream of hot gases continuously ejected from the solar corona. In case you do not know the meaning of a solar corona, it is the outermost atmosphere of the Sun. Amazingly, the thin streams of high gases move at a speed of approximately 400 kilometers (250 miles) per second (as cited in Yeomans 1991 p. 185). In addition, a comet frequently also displays smaller, curved tails composed of fine dust particles blown from the coma by the pressure of solar
