What else can I help you with?
What period of time does the sun take to complete one trip around the sky along the ecliptic?
The sun takes about 365.25 days to complete one trip around the sky along the ecliptic, which is why we have a year with that duration.
If there is a lunar eclipse on the vernal equinox is the moon above the ecliptic?
During a lunar eclipse, the Earth is positioned between the Sun and the Moon, causing the Earth's shadow to fall on the Moon. The vernal equinox marks the time when the Sun crosses the celestial equator, and the ecliptic is the apparent path of the Sun across the sky. If a lunar eclipse occurs on the vernal equinox, the Moon would be aligned with the ecliptic, meaning it would not be above it, but rather in the same plane as the ecliptic.
What path does a planet follow across the sky?
Planets in the solar system except Pluto orbit the sun along the ecliptic. The ecliptic is an imaginary line like the equator round the Earth. The rings of Saturn give you a good analogy. Pluto is probably a captured asteroid and not part of the original solar system. It's orbit dips above and below the ecliptic like the moon around the Earth
Why doesn't a lunar eclipse happen every time there is a full moon?
Because the moon's orbit is slightly inclined from the plane of the ecliptic. The ecliptic is the path that the sun appears to follow in the sky, caused by the path of the earth's orbit around the sun. The moon's orbit is inclined about 5 degrees from the plane of the earth's orbit around the sun. The moon crosses the ecliptic about twice per month. If this happens during a new moon, a solar eclipse occurs, during a full moon, a lunar eclipse occurs. http://csep10.phys.utk.edu/astr161/lect/time/moonorbit.html http://en.wikipedia.org/wiki/Ecliptic http://en.wikipedia.org/wiki/Moon
How can you locate the position of vernal equinox in the night sky?
To locate the position of the vernal equinox in the night sky, you can look for the point in the sky where the ecliptic intersects the celestial equator. This point roughly corresponds to the constellation Pisces. However, it's important to note that the vernal equinox moves slightly over time due to precession.
Can you see the Milky Way all the time?
You're in Milky way!!! At night time, if you can see a cloudy band stretching across the plane of the ecliptic, that's the Milky Way Galaxy, from our point of view, anyway.
Where would the ecliptic be in the northern hemisphere?
This is difficult to describe in text, without sketches, but I'll try: -- First, the 'equator' of the sky: That's a line all around the sky that's exactly over the Earth's equator. In your sky, wherever you are, this 'celestial' equator is a semi-circle from the exactly-east point on your horizon to the exactly-west point. Its highest point is due south of you, and at that point, its height above your southern horizon is (90 degrees minus your latitude). If you're on the equator, then the celestial equator passes right over your head. If you're at the north pole, then the celestial equator coincides with your horizon. If you're in Minneapolis, Salem OR, Bangor, Grenoble, Torino, or Belgrade, at 45° north latitude, then it passes 45° above your south horizon. -- The highest of the 3 stars in Orion's belt is on the celestial equator. -- The ecliptic is another line all the way around the sky. It crosses the celestial equator at two places, and it's tilted 231/2 degrees to the equator. So half of the ecliptic is above (north) of the equator, and the other half of it is below the sky's equator. -- Through the day, as the Earth turns, one of the two points where the ecliptic crosses the equator will be in your sky at any one time. The ecliptic will appear high in your sky for half of the day, and low in the sky for the other half. The point where it crosses directly south of you will wiggle up and down through a total of 47 degrees in 24 hours. -- The left pincher of Scorpius and the heart of Leo (Regulus) are on the ecliptic. The eye of Taurus (Aldeberan) is not too far off of it. The ecliptic is actually the line where the plane of Earth's orbit cuts through the 'bowl' of the sky. Some of the results are: -- The sun is always on the ecliptic. -- The planets are always close to the ecliptic. Now, in mid-2013, Jupiter is smack on it. -- The moon is always within about 51/2 degrees of the ecliptic. -- In Summer, the sun is high, so the ecliptic ... with the moon and planets ... is low during the night. -- In Winter, the sun is low, so the ecliptic ... with the moon and planets ... is high during the night. Remember those two points where the ecliptic crosses the celestial equator ? Those points in the sky are the 'equinoxes'. Those points are where the sun is on March 21 and September 21.
Why had the Romans not conquered the Gauls yet?
Please specify the point of time you are referring to and whether you are referring to the Gauls of northern Italy or the Gauls of of central and northern France.
When is the sun lowest in the sky?
The sun is lowest in the sky during the winter solstice, which usually occurs around December 21st in the Northern Hemisphere and around June 21st in the Southern Hemisphere. At this time, the sun is at its most southern or northern point, resulting in the shortest day of the year.
Where do all the planets orbits occur on the celestial sphere?
On the celestial sphere there is a line that goes all the way round, called the ecliptic. It is the apparent path of the Sun against the background stars, as the Earth revolves in its orbit. The ecliptic is not the same as the equator (the two planes are inclined by 23½ degrees) but it crosses the equator at two points. The ecliptic defines the plane of the Earth's orbit, because actually the Sun stays where it is while the Earth revolves. The other planets' orbits are almost exactly in the same plane as the Earth's, which means that all the planets stay close to the ecliptic all the time. So a planet's position is pretty well defined by its longitude on the ecliptic, measured from a special point called the First Point of Aries, which is where the Sun is at the Spring Equinox. It is a direction defined by the intersection of two planes, the Earth's equator and the ecliptic. Unfortunately this fixed direction, which is used as the basis of the geocentric spherical-coordinate system (right-ascension and declination), is not itself actually fixed, but it moves right round the ecliptic every 25,000 years, so star atlases have to be redrawn and republished every 50-100 years.
Which position of earth represents winter time in the northern hemisphere?
None. When spring starts in the northern hemisphere, autumn is starting in the southern hemisphere. There are only ever 2 seasons at any which point in time.
What period of time does the sun take to complete one trip around the sky along the ecliptic?
The sun takes about 365.25 days to complete one trip around the sky along the ecliptic, which is why we have a year with that duration.
What direction of the compass does the shadow point to at midday?
At midday, when the sun is at its highest point in the sky, shadows typically point directly north in the Northern Hemisphere and directly south in the Southern Hemisphere. This is because the sun is positioned in the southern part of the sky in the Northern Hemisphere and in the northern part in the Southern Hemisphere. The exact direction can vary slightly depending on the time of year and the observer's latitude.
If there is a lunar eclipse on the vernal equinox is the moon above the ecliptic?
During a lunar eclipse, the Earth is positioned between the Sun and the Moon, causing the Earth's shadow to fall on the Moon. The vernal equinox marks the time when the Sun crosses the celestial equator, and the ecliptic is the apparent path of the Sun across the sky. If a lunar eclipse occurs on the vernal equinox, the Moon would be aligned with the ecliptic, meaning it would not be above it, but rather in the same plane as the ecliptic.
What was most true in northern US cities?
people had many choices about what to do with their free time.

Were is the sun at 12pm in the day?
At its highest point in the sky that it will reach at any time in the day. Highest in the southern sky if you're in the northern Hemisphere, and highest in the northern sky if you're in the southern Hemisphere. (Ambiguous in the Tropic zone, depending on the time of year.)
