Does the star Betelgeuse really tell direction?
The star you're looking for to tell direction is Polaris, the North Star.
If you know what time it is, and have an accurate star map, you could use Betelgeuse to tell direction, but it's difficult.
By it's spectrum. If it appears blue or white then it is hotter than a red or orange star. Rigel is a blue-white star whereas Betelgeuse is a red star.
The position of Betelgeuse in the sky is a function of the date and your location. I recommend the open-source planetarium program "Stellarium", which will tell you, for any location and date you specify, the location of any star or planet in the sky.
It tells the astronomer the general direction in which the star is located.
Sailors used a compass or an astrolabe. a compass points North so you know your direction. an astrolabe can tell your location by using the sun as a reference point but you might need a star chart to use it. If you were traveling at night you would use the star char5t and the North Star to tell direction.
look at it through a telescope
a way to tell if a star has planets is to observe a wobble in its position. i.e when a planet orbits a star it pulls at it making the star move slightly in its direction. when seen from far away it looks like the star is moving back and forth. This is a very rough explanation and can no doubt be improved upon.
The star is called a compass rose, which is used to tell direction on maps. the top of the star points towards the north, the left to the left to the west, the bottom to the south, and the right to the east.
Emission spectra tell us about the elements in the surface layers of the star. They can also tell us the star's relative motion (each element has a characteristic spectrum, so how much, and in which direction, the lines are shifted tells us how quickly the star is moving towards or away from us).
It's really hard to tell from that description, but it could possibly be a neutron star.
A star is a bright shiny thing in the sky.But well I dont really know if you can but you most likely could if you were smart enough,and if you had a really good telescope and you knew how to.
The simple answer is by looking at them. The technical answer is by analysing their bolometric luminosity with a bolometer.
I really do not know but I am sure the have a fan blog that will probably tell you their rout
You can't really tell they don't have set days. Just be on the look out!
mattybraps is hot and awesome if someone really knows where he lives tell me
you cant really tell the temperature of a star but you tell about hot it is by color. blue being the hottest and red being the coldest.
That's two stars. - If you tell us where you saw them, at least in what direction, and when, it might be easier to identify the specific stars.
"Star Ranks", Arent really ranks they just kinda tell you what level your on. IF YOU WANT ME TO ANSWER YOUR QUESTION EMAIL ME AT DANAGIRL444@GMAIL.COM ~SiMqUeSt~
Many, many things. A stars distance, age, speed, direction, type, size, location, composition, temperature to name just a few.
Which is more reliable method for a sailor to determine noth by using the star Polaris or reading afoad map?
A map doesn't tell you which way is north, it tells you which direction to go to get somewhere assuming you already KNOW which way is north... so it's not really an option except in special cases (for example, if a map shows two landmarks that are visible from the sailor's current position, he can use that to determine both where he is on the map and which direction is north).
Nobody can possibly tell you the names of all the droids but if you really want to know I recommend the book "Star Wars: The New Essential Guide to Droids."
You can tell in which direction the animals are walking by studying their footprints. Determine which directions their feet are pointed to see which direction they are traveling in.
Speed is a scalar quantity and has only magnitude and not direction. Hence, speed cannot tell us what direction an object is moving. However, velocity which is the vector equivalent of speed, can tell us the direction.
It's really simple. It's talking about how this girl doesn't realize she's beautiful, and that she's insecure. One direction or the boy singing it, thinks she is beautiful and he is trying to tell her that.
That is a really odd question and why don't you ask them yourself,they would probaly be happy to tell you espicially Harry.
Being from St. Louis myself and studyin the weather the past 10 years or so I can tell you that there isn't really a predominent wind direction for us. We get mostly south winds during the summer we get north winds during the winter and it blows from the west and sometimes from the east so there is no really predominent wind direction for us.
All object are traveling in different direction and speed. If you believe that the universe has edge, then all direction will point to that edge. Unfortunately, no one can really tell if the universe has edge.
A compass will tell you which direction you are traveling in.
You tell by your month and day. For example, December 29 is Capricorn, and November 29 is Sagittarius. I'm not really bothered telling you which month and day is which! Sorry. You can ask though that is what Answers.com is for!
I love all of pop star from one direction they are soo cute and i'm going to call there manger and asked him or her if they can come sing to my birthday party i had a justin bieber party last time and this year it is on direction the whole thing i hope they come i really want them to come if not i'm going to be sad and unhappy and all my cousin… Read More
If you call it "velocity" then you have to tell what direction it points. If you only tell how fast it is but you don't tell the direction, then it's "speed", not velocity.
It does so by indicating the direction to the magnetic pole.
Your can tell the general temperate of a star, visibly, by noting its color.
All of the constellations that we can see are actually in our own galaxy, so we can't really answer your question as it was asked. The closet star to earth other than our own sun is the star Proxima Centauri, we can tell by the name that it is in the constellation Centaurus.
im not really sure but if anyone has svr2009 plz tell me how to get rvd's fivestar frog splash. ty
At night, you can tell time by using the Big Dipper's pointer stars to the North Star. Imagine an hour hand on a clock - the direction it's pointing indicates the approximate time. More on http://oliodigest.com/science/astronomy/tell-time-by-the-big-dipper-constellation.html
It tells you which direction the wind is blowing from by pointing that direction.
A 'vane' will tell you wind direction.
You can tell by if she does things to make sure that you can see. She might always look at you and when you look at her direction she will turn to another direction fast.
Kelly Clarkson wrote Tell Me A Lie for One Direction.
I have been dating a man for 3 months and as this is the longest I have been with someone i want to know how can you tell when it's heading in the right direction?
you can know when because if you really love him and he loves you you can feel it
Only one direction can tell you that.
I don't really know. But i think it is about giving people a fantasy of space and sci-fi. To give you this weird but awesome world of day dreaming. However has watched Star Wars Please tell us!
Wind vanes are used to tell the direction in which the wind is blowing. Farmers would use it to tell the direction of the wind when out in the field.
im not sure, hard to tell In the manga Cowboy Bebop:Shooting Star, they say he's Oriental. They don't really say anything else on it.
Polaris is the north star, being possitioned directly above the north pole it doesn't move from it's spot in the nigth sky, this can be used to both tell direction and time at nigth without a compass or a watch.
All stars can be used to tell which direction you are travelling in as the movement of the earth is in a consistant direction, allowing you to compare your movement with the direction that the stars are travelling in.
It really depends on the stage of cancer, and the will and strength of the person, unless the cancer becomes overpowering, as well as the actions taken to fight against it. Treatment and what not. With cancer really there is no way to tell. It takes miracles either direction.
Speed and direction combined produce velocity, which is a vectory notation.
how hot the star is and how big it is.
when its glowing its a star
