Comets are dirty balls of snow made of water, carbon dioxide, ammonia, methane ice, and dust. Comets are primarily composed of ice, which is quite...Become a member and unlock all Study Answers Start today. Try it now Creat...
So molecules like this ended up on Earth. In fact, what we call meteorites are pieces broken away from comets and asteroids that came in our atmosphere and left their extra-terrestrial organic matter on the surface of primitive Earth.这样的分子最终来到了地球上。事实上，我们所说的陨石是来自彗星...
What are comets from the Oort cloud called? An icy leftover planetesimal orbiting the sun is called When in the solar cycle do sunspots form? What separates the inner and outer solar system? The intense magnetic fields of sunspots cause arch-like eruptions called: a. solar eclipses b. coron...
Comets don't become round with their own gravity due to their limited size, so they will often have irregular shapes. Comets are visible from Earth when they pass through the inner solar system. They become more visible as they approach the brightness of the sun. The nucleus of a comet on...
Globular clusters do tend to be composed of old stars, but not entirely. Some of them (e.g., Omega Centauri) have a mix of stars of different ages, implying that there are episodes of star formation within the cluster over billions of years. But yes, the oldest generation of stars can...
Comets are primarily made of dust, rock, and ice, and as they approach the sun they warm up and give off water and dust particles (which form comets’ distinctive tails). We are used to observing average-sized comets which eject gases, giving the comet a tiny kick and changing its traje...
Comets are known to be remnants of the early solar system but their numbers are very uncertain. Each year several dozen new comets are discovered. Most asteroids orbit the Sun in nearly circular paths lying between Mars and Jupiter. Comets originate in the outer fringes of the solar system, ...
There are 6 steps to draw the Lewis structure of Formaldehyde. Step 1: Determine the total number of valence electrons in the Formaldehyde. Hydrogen, a Group IA element, has one electron in its outer shell. Oxygen, a Group VIA element, has six electrons in its outer shell. Carbon is a ...
However, people started referring to Comet 12P/Pons-Brooks as the devil comet in 2023 because of explosive activity on its surface. Generally,comets are made up of materialssuch as dust, gas, and ice, and scientists think that the devil comet is cryovolcanic. The reason is because the dust...
How Do Comets Produce Meteor Showers? Figure 4: A NASA image of Comet Hale-Bopp, showing its two tails. Comets are small bodies composed primarily of ice with a little bit of sand or gravel. A typical comet's nucleus is a few miles across. It spends most of its time in a lazy, ...
