Constellations found on Northern Hemisphere

Answer 1

The question is unclear. Constellations are simply areas of sky and don't have an unambiguous "brightness." The star with the brightest apparent magnitude is in Canis Major, so that's as good an answer as any other.

Answer 2

That would have to be the "sword" in Orion.

Look south in the early evening during the winter months. Orion is a very large rectangle of bright stars.
The most instantly recognizable feature will be three relatively bright stars in a straight line, representing
the hunter's 'belt', and the 'sword' is a long skinny hazy patch hanging down from the belt. You can see the
haziness with the naked eye, and begin to appreciate the nebulosity with any kind of telescope or binoculars.

Answer 3

This really various depending on where you are, however all together, it is very hard to know. If you merely look in the right place, you will instantly see thousands upon thousands of stars, using a telescope however, this then becomes millions.

This cant be calculated accurately, because it would be easy to recount a star, however as technology progresses, we might know fully.

Astronomers estimate there are about 100 thousand million stars in the Milky Way alone.

Answer 4

All of them, if you know the sky well enough.

Were you standing on the north pole looking straight up, Polaris would be directly overhead. Consequently if you are anywhere in the northern hemisphere, Polaris indicates north.

Answer 5

According to PlanetFinder you can see Mars and Venus in the eastern sky, and Jupiter in the western sky in late July 2009. You can see them with the naked eye. See the website http://www.lightandmatter.com/area2planet.shtml

That link didn't work but I have one that should help. Jupiter and two(?) of its moons are visible tonight. www.space.com/spacewatch/sky_calendar.html

Answer 6

All planets are visible in the night sky, depending on time, you can only see certain plants in certain parts of the world. You have to be somewhere completely dark with no city lights. Planets can be told apart from stars because stars tend to "twinkle'' and planets do not.

The link for StarDate (below) will give a day-by-day guide to what planets are visible.

Answer 7

Astronomical visibility from the South Pole is some of the best on earth. The view is through the largest part of the galaxy toward the Southern Hemisphere of stars. From there, depending on the season, you can see such constellations as:

Southern Circumpolar Constellations

• Carina Centaurus
• Southern Cross

Southern Spring Constellation

• Andromeda
• Aquarius
• Capricornus
• Pegasus
• Pisces

Southern Summer Constellations

• Canis Major
• Cetus
• Eridanus
• Gemini
• Orion
• Perseus
• Taurus

This list is according to a Google search for Southern Hemisphere Constellations.

Answer 8

At any given point on Earth, the point directly overhead will have the same declination as your latitude position (+ for north latitude, - for south latitude). You can see approximately 90 degrees north and south from that assuming there are no obstacles (mountains, buildings, trees, etc.) on the horizon. So, if you live at latitude 40 N, then +40 declination would be directly overhead. For you, stars with declinations higher than +40 appear to never set. To the south, it's trickier, because what's visible depends not only on declination but on the right ascension and the time of year, but any star with a declination of higher than -50 should be above the horizon at SOME point during the year.

Answer 9

According to (See Related Links), the following Constallations can be seen on different seasons in the night sky:

* Canis Major * Cetus * Eridanus * Gemini * Lynx * Perseus * Taurus * Anguilla

* Cygnus * Hercules

* Lyra * Ophiuchus

* Sagittarius

* Scorpius * Andromeda * Aqarius * Caprinicus * Pegasus * Pisces * Bootes * Cancer * Crater * Hydra * Leo * Virgo

Answer 10

There are 88 "officially recognized" constellations, according to the International Astronomical Union, the IAU. Everybody will have their own favorites, of course, but in my opinion the top two "most commonly known" constellations include the Big Dipper and Orion the Hunter.

Beyond that, there are twelve "signs of the Zodiac", constellations that lie along the ecliptic.
