Which of the following planets is NOT a gas giant? a. Earth b. Jupiter c. Saturn d. Uranus 16. The sun gets its energy from a. burning fuel b. nuclear fusion c. shrinking due to gravity d. convection 17. The number of on any planet can be used to estimate how old the surface is.
If Jupiter were a shell, all the other planets and their moons could fit inside with room to spare. Jupiter could hold 317 of our earth's. Jupiter's diameter is 88,000 miles, thirty times the width of the United States. It orbits the sun at 8.1 miles per second (mps), or 19,160 miles per hour (mph). It is 485 million miles from the sun making it a very cold planet in the range of minus 240 degrees F. However, due to the enormous pressure of its mass, the center is estimated to be 54,000 degrees F., or five times hotter than the surface of the sun.
Pluto’s orbit is very different, because it orbits the opposite direction that the other planets do. Pluto is so cold that it is more than negative 235 degrees Celsius. No One knows what Pluto is made up of. Dome scientists say that it is 50–70 percent rock and 30–50 percent ice. The composition is nitrogen and oxygen.
Sunspots and Flares Our Sun, the 5-billion-year-old star that sustains life here on Earth, powers photosynthesis in green plants and is ultimately the source of all food and fossil fuel. The connection and interaction between the Sun and Earth drive the seasons, currents in the oceans, weather and climate. With a core reaching a fiery 16 million degrees Kelvin (nearly 29 million degrees Fahrenheit), the Sun's surface temperature is so hot that no solid or liquid can exist there. As early as the fifth century B.C., the Chinese reported having observed dark spots on the sun. In 1960, Galileo Galilei of Italy, Johannes Fabricius of Holland, Christopher Scheiner of Germany, and Thomas Harriott of Englandeach independently

Because its density is so high, neutrons spin in the same way that electrons do so must obey the Pauli Exclusion Principle. 6. A pulsar does not pulse, it emits beams of radiation that sweep around the sky as the neutron star rotates, and astronomers detect pulses when they sweep over the Earth. 11. Sometimes in binary systems, mass flows into a hot accretion disk around the neutron star and causes the emission of x rays.
Prominences 1. Prominences are immense clouds of glowing gases that erupt from the upper chromosphere. 2. The loops or arches of gases may shoot as high as 100 000 kilometres from the surface of the Sun. This allows some of the surface gases, mainly hydrogen and helium, to escape into space.
However, if the planet's carbon cycle has ceased due to lack of oceans and plate tectonics, Kepler-22b may turn out to be a searing, sterile super-Venus. Climate and habitability The average distance from Kepler-22b to its host star Kepler-22 is about 15% less than the distance from Earth to the Sun but the luminosity (light output) of Kepler-22 is about 25% less than that of the Sun. This combination of a shorter average distance from the star and a lower stellar luminosity are consistent with a moderate surface temperature at that distance if we assume that the surface is not subject to extreme greenhouse heating. If the planet is found to move in a highly elliptical orbit, its surface temperature will vary from a higher temperature when close to Kepler-22 to lower when further away. If the orbit is indeed highly elliptical, then the temperature variance range will be extreme.
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
General Science Space Topic: Web Quest on Planets Mars General Science Space Topic: Web Quest on Planets Mars Namesake: Mars Distance from the sun: 22.8 Million Km Diameter: 6792 Km Period of Revolution: 686 days Rotation Period: 24 hours 39 minutes and 35 seconds Moons: Mars has two moons Phobos and Deimos Atmosphere: It consists of 95% Carbon Dioxide, 3% Nitrogen, 1.6 Argon Temperature: The night time temperatures fall well below zero. On those summer days, it can be around 20 degrees Celsius then plummet to -90 C at night. Composition: Mars is made of rock and iron oxides. It's surface is covered in mountains, volcanoes, valleys, ice caps and dried up river beds. Mars is also very dry like a desert.
