AN acrux is a crux star ( southern cross)

4.Are there any planets that orbit this star? Tell me about them.

There are no planets that rotate this star it actually orbits the milky way.

Astronomy Topics

There are many choices that I have for my astronomy project. One topic that I can do is black holes. A black hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull. Anything that gets sucked into this black hole cannot get out. Not even light is safe from this menace. Anything that enters the hole will be crushed into a smaller matter.
The Moon, of course, has been known since prehistoric times. It is the second brightest object in the sky after the Sun. The moon orbits the earth once per month. And yes if you didn't know the moon im talking about the earths moon. Almost every planet has at least one moon. I say at least because some planets have more than one moon.
Worm holes are very unique holes...or should I say tunnels that connect two or more points in space. One thing you should know is that they are highly unstable and would probably collapse instantly if even the tiniest amount of matter. Worm holes are very dangerous but if we can learn to control them we can start traveling anywhere in space.
Mars is the fourth planet from the Sun and is commonly referred to as the Red Planet. The rocks, soil and sky have a red or pink hue. The distinct red color was observed by stargazers throughout history. It was given its name by the Romans in honor of their god of war.Before space exploration, Mars was considered the best candidate for harboring extraterrestrial life. Astronomers thought they saw straight lines crisscrossing its surface. This led to the popular belief that irrigation canals on the planet had been constructed by intelligent beings.
The big bang theoryis an effort to explain what happened at the very beginning of our universe. Discoveries in astronomy and physics have shown beyond a reasonable doubt that our universe did in fact have a beginning. Prior to that moment there was nothing; during and after that moment there was something: our universe. The big bang theory is an effort to explain what happened during and after that moment. There are many misconceptions surrounding the Big Bang theory. For example, we tend to imagine a giant explosion. Experts however say that there was no explosion; there was (and continues to be) an expansion. Rather than imagining a balloon popping and releasing its contents, imagine a balloon expanding: an infinitesimally small balloon expanding to the size of our current universe.

Factors that effect wind

1. The 3 factors that effect wind are pressure differences, corolis effect, and friction.

2. Corolis effect because the earths rotation can effect the weather and wind directions

3. If earth stopped rotating the earths weather would become boring and predictable.

Cloud Types


1. Three types of low clouds are Stratocumulus clouds,Stratus clouds, and Cumulus clouds. Three types of middle clouds are Altocumulus clouds, Altostratus clouds, and Nimbostratus clouds. The three types of high clouds are Cirrus clouds, Cirrocumulus clouds, and Cirrostratus clouds. The only vertical cloud is the cumulonimbus cloud. My favorite clouds would have to be the cirrus clouds they remind me of a lot of animals. Low clouds can bring drizzle rain, middle clouds can bring warm, and humid temp. first but then turn to thunderstorms. Lastly high clouds can bring ice and rain.
