What causes the tail of a comet

solar wind The heat from the sun

How many moons does Pluto have

Pluto has five known moons:

  1. Charon, the largest one, Charon was discovered in 1978.
  2. Hydra, very small
  3. Nix, very small, and two more-newly discovered small moons. and Nix/Hydra were identified in 2005.
  4. Kerberos (provisionally named P4 or S/2011-134340)
  5. Styx (S/2012-134340). On July 11, 2012, it was announced that a team of astronomers, using NASA's Hubble Space Telescope, discovered a fifth moon orbiting Pluto. The moon is provisionally designated as S/2012 (134340) 1. The moon was discovered by astronomers using nine sets of images taken by the Wide Field Camera 3 fitted to the Hubble Telescope between June 26, 2012 and July 9, 2012. It is estimated to be an irregular shape and 6 to 15 miles across.

The largest moon, Charon, is proportionally larger compared to its primary than any other satellite of a known planet or dwarf planet in the solar system. In fact there is some discussion as to whether we should consider this a "binary system" instead of a dwarf planet with moons because Charon is so massive that the barycenter (center of gravity around which the bodies rotate) of the Pluto-Charon group is not inside either of those bodies.

Which terrestrial planet is the largest

Earth

Which planet experiences the widest range of temperatures

Mercury experiences the widest range of temperatures in our Solar System.

Because it's a very slowly-rotating planet, and because it has no blanketing atmosphere, its "dark side" can stay that way for a long time, allowing temps to plunge hundreds of degrees. On the other hand, being the closest planet to the sun, Mercury's hot side is very hot indeed!

The best estimates are that Mercury's hot side gets up to 465 deg. C, and the cold side can chill to -184 deg. C. That's a range of 649 deg. C, or 1,168 deg. Fahrenheit.
Mercury the day time temprature is as high as 800 degrees and at night it is as low as -300 degrees. There is little atmosphere to retain the heat giving such an unusuall temprature change.

What aspect of the gas giants has the biggest effect on their rings and satellites

The aspect of the gas giants that has the biggest effect on their rings and satellites is their gravity.

Why are temperatures on the gas giants so low

They are far from the sun.

The sun produces energy from matter in its core through the process of

fusion

What do all of the terrestrial planets have in common

They all have solid, rocky surfaces.

Which planet do most known extrasolar planets most resemble

Jupiter Neptune

The planet that most extrasolar planets resembles Jupiter.

Jupiter(apex)
Most of the confirmed Exoplanets are larger gaseous planets with large masses. These are easier to detect and confirm due to their size. They most resemble Jupiter, although many are thought to be much larger than our largest planet.

Which best describes how the sun rotates

The sun rotates more slowly at its poles.

Why are three of Saturn's satellites -- Atlas Prometheus and Pandora -- called shepherd moons

They keep Saturn's rings in order

Why do astronomers find it difficult to locate extrasolar planets with telescopes

Planets are considerably smaller than their parent stars, also they emit no light and are very close to the star. With all this combined, separating between the two with a telescope is very difficult.

The sun rotates

at different speeds along its sphere.

Of all the rocky planets Mercury is the one humans are most likely to colonize

false

Which is true of the satellite Titan

It is larger than the planet mercury.

Solar flares may be seen in the suns

You can see Solar Flares in the Suns' Corona.

Which is true of saturns satellite titan

its larger then the planet mercury

Energy released during nuclear fusion

gamma ray photon

What is true about the satellite titan

That it is Saturn's biggest moon and it has an atmosphere.

All the rocky planets Venus is the one humans are most likely to colonize

False

A stream of plasma

coronal mass ejections

In which layer of the sun are gamma ray photons produced-

The core

The atmosphere of the gas giants is usually made up of mostly of hydrogen and what

The atmosphere of the gas giants is usually made up of mostly of hydrogen and what?

Humans breathe in oxygen and release gas.

carbon dioxide

What Of all the gas giants has the longest period of revolution.

Neptune

How many moons does Saturn have

Saturn has 82 moons. Fifty-three moons are confirmed and named and another 29 moons are awaiting confirmation of discovery and official naming.

Which planet has high temperatures due to the runaway greenhouse effect

venus :)

Which is true of pluto

Pluto has a moon that is about half its size

Why is one side of the moon called the dark side of the moon

The side of the moon that we can never see from Earth is often called the "dark side" (a) because it sounds cool, and (b) because darkness is a powerful metaphor for the unknown. In fact, the so-called dark side of the moon is not really dark. Luna has day and night on every part of its surface (just like Earth, only Lunar days are 28 Earth days long). During a new moon, for instance, the "dark side" is flooded with light.

The far side of the moon is dark in the metaphorical sense, in that we never see it. To people who think visually (most of us), lack of information seems like darkness.

How is it that there's a part of the moon we never see? Like many moons of planets in our solar system, our moon, Luna, keeps one side to its primary continually (there's a little wobble, so we can really see about 55% of the lunar surface). The moon is "tide locked" (read about tidal locking on wikipedia). This situation develops with all moons and planets over a long time. The Earth's rotation is slowing, too, and will eventually become tide locked to the sun (not for a very, very, very long time, but scientists can measure the tiny lengthening of the day).

Quibble: to be fair, the far side of the moon does receive less light than the rest of the moon, because it doesn't see any of the sunlight reflected from the earth. So technically, it is a bit darker overall. But nearly nobody who uses the phrase "dark side of the moon" is thinking of it in this way.

Which contributes to the lack of evidence of the period of heavy bombardment on earth

Plate movements

which of the following is the cause for the different seasons on earth

the way earth has a tilted axis
