We won't know the answer to that question until we know that we have discovered
all of the stars above the horizon in the northern hemisphere, and measured the
brightness of each one.
In fact, now that we ponder the question some more, it's obvious that the question can
never be answered. The least bright star can't be detected, even by the most powerful
telescope, so we're not even aware that it exists.
What else can I help you with?
Is Sirius visible at night in the northern hemisphere during the summer?
Yes, Sirius is a bright star and is visible in the northern hemisphere during the summer months. It is one of the brightest stars in the night sky and can be seen low on the horizon in the southeast during the summer evenings.
What is the name of the very bright star this period situated to the west around midnight Addressed to those living in the northern hemisphere?
That would be Jupiter - which technically isn't a star, but a planet. However, it looks just like a star. Also, since it is near the Ecliptic, it can be seen both in the northern and southern hemisphere. (Answered in January 2012 - at other times, the answer will vary - other bright stars or planets may appear.)
Where is Lyra the constellation located?
Lyra contains the third brightest star in the northern hemisphere, Vega. From spring to autumn, it is clearly visible, while during the winter months, it is visible low on the northern horizon.
Why an observer in the southern hemisphere cannot see the star polaris?
Polaris, the North Star, is located near the North Celestial Pole which is visible only from the Northern Hemisphere. In the Southern Hemisphere, there is no bright star close to the South Celestial Pole like Polaris because the South Celestial Pole does not have a similarly positioned bright star. Therefore, observers in the Southern Hemisphere cannot see Polaris due to its location in the sky.
What star is the brightest in northern hemisphere?
After the Sun, the brightest star is Sirius, in the constellation Canis Major. However, while Sirius is the brightest star visible from the Northern Hemisphere, it is part of a southern hemisphere constellation. Therefore, Arcturus, in Bootes, would be the brightest Northern Hemisphere star.
What exactly is the north star?
It is a star called Polaris. It is not a particularly bright star. It is important though. As seen from the Northern Hemisphere, it is normally seen to be in the same location and all other stars appear to rotate around that point.
What imaginary point around which southern hemisphere stars rotate is south pole?
In the northern hemisphere, we have a moderately bright star called 'Polaris' or the 'North Star' ... that happens to be located near the north pole of the sky, and the stars appear to revolve around it once a day. The stars appear to do the same in the southern hemisphere. But it's a little less obvious, because there's no particularly bright star near the south pole of the sky.
What hemisphere is little dipper in?
The Northern hemisphere. The star at the end of the handle of the "Little Dipper" is Polaris, the North Pole star.
Will Jupiter be visible on October 31 2009?
Yes. If you live in the northern hemisphere it has been visible for many months now, looking like a bright star towards the south.
What was the disadvantage off using the north star to determine direction?
One disadvantage of using the North Star to determine direction is that it can only accurately indicate direction in the northern hemisphere. In the southern hemisphere, there is no equivalent bright star to serve as a reliable directional marker.
Can the southern hemisphere people see the pole star Why?
The elevation of Polaris (the North Star) above the Northern horizon is almostequal to the North latitude of the place where you are when you see it.That means that when you stand on the Equator, the North Star is exactlyON the Northern horizon, and if you stand anywhere South of the Equator,the North Star is always BELOW the horizon.But . . .Everybody in the Southern hemisphere CAN see the SOUTH pole of the sky,which nobody in the Northern hemisphere can ever see.Sadly, there's no bright star anywhere near the South pole of the sky,to mark it the way Polaris marks the sky's North pole for us.
Which is bigger Orion or northern hemisphere?
Orion is a star. It is much bigger than the entire planet Earth, much less the northern hemisphere.
