As you stand in the middle of a playground or while you are sitting in your class, there is an immense weight right over your head, but you do not feel it! This is the weight of the atmosphere, or air, as we know it. Composed of nitrogen, oxygen, carbon dioxide and other gases,...
Which layer of the atmosphere protects Earth from meteoroids? Which gases made up most of Earth's early atmosphere? What are planetary systems made of? Does Eris orbit the sun? What is Halley's Comet made of? What is outer space made of?
Pluto was once considered the ninth planet of our solar system. However, the discovery of other planet-like objects caused the International Astronomical Union (IAU) to create three criteria for planetary status. Unfortunately, Pluto failed the third criterion of clearing all large objects from its...
though the characteristics are more similar to the shield volcano. Like a shield volcano, cinder cone volcanoes feature basaltic lava. However, their lava is slightly thicker. This allows for the trapping of some gases. Typically, these eruptions eject small clumps of lava, called bombs, which ...
In the case of entanglement, the information that appears at your Pluto measurement station is not useful information (in the ordinary sense). It is random just like the random result that came out of that first measurement (but matching random). So, the key point is that you could not ta...
The moon's atmosphere is classified as an exosphere due to its extremely low density. At 100 molecules per cubic centimeter, this layer of gases is nearly indistinguishable from empty space. In fact, the entire mass of the moon's exosphere is only 55,000 pounds. That's roughly the same ...
What Would It Be Like to Live On Dwarf Planet Ceres in the Asteroid Belt? The dwarf Planet Ceres may be round, but it doesn't have much of an atmosphere to speak of. What would it be like for human explorers if they visited this object in the asteroid belt between Mars and Jupiter?
Saturn also has a moon called Titan and it has its very own atmosphere. Many of the Moons that are farther from theSunare made of gas, dust, and ice form ring. If the Moon did not exist the Earth would wobble violently. The shifts in the angle of the Earths tilt of 23.5 degrees ...

A comet is an icy object which is present in a Solar System object that, when travelling close to the Sun, warms and starts to emit gases, a practice known as outgassing. This creates a visible atmosphere or coma, and sometimes also a tail. These occurrences are due to the effects of...
