Only at the equator are all the stars visible over the course of the year?
At the equator, due to the earth's rotation, observers have a complete view of the sky including all stars over the course of a year. This is because the equator lies halfway between the poles, where the stars around the celestial poles are always visible. In contrast, at higher latitudes, some stars are not visible due to the earth's tilt and the respective hemispheres facing away from certain stars at different times.
Explain why stars appear to move across the sky each night why are some stars only visible doing certain seasons?
Stars appear to move across the sky each night because the earth is moving, but not the stars. Also some stars are only visible during certain seasons because as the earth rotates, they become visible.
How would the stars' motions differ at the equator of the earth?
At the equator of the Earth, stars appear to rise directly in the east and set directly in the west, following a straight path across the sky. This motion is more pronounced due to the Earth's rotation being perpendicular to the celestial equator. As a result, stars at the equator also rise and set more quickly compared to locations at higher latitudes, where they travel in a more diagonal path across the sky. Additionally, observers at the equator can see a wider variety of stars throughout the year, including both northern and southern celestial hemispheres.
What do the Celestial equator and the horizon have in common?
The celestial equator and the horizon are both reference planes used in astronomy to locate celestial objects. The celestial equator is an imaginary line that divides the celestial sphere into the northern and southern hemispheres, while the horizon is the boundary between the sky and the Earth, marking what is visible from a specific location. Both concepts are crucial for understanding the positions and movements of stars and planets as observed from Earth. Additionally, they are both perpendicular to the axis of rotation of the Earth.
Are the stars visible at 7pm still visible at 11pm in their original position why is this so?
No, the stars visible at 7 PM are not in the same position at 11 PM due to the Earth's rotation. As the Earth rotates on its axis, stars appear to move across the night sky, changing their positions relative to an observer. This apparent motion is a result of the Earth's rotation, causing stars to rise in the east and set in the west over the course of several hours.

Is it true onle at the equator are all the stars visible over the course of the year?
If you're willing to depart now and then from a routine schedule of sleep and stargazing, you can probably see all of the constellations and visible stars in the sky within a period of a few months, from an observing location on the equator.
What hemisphere is the constelation Aries in?
There are no constellations in the northern hemisphere, but several of them are visibleto observers located there.Depending where you are in the northern hemisphere, you can see anywhere betweenhalf of all the visible stars (from the north pole) to all of the visible stars (from the equator).At any location on earth, Aries is visible during some part of the year.
What are 2 stars visible from earth?
two stars are the sun and betelgeuse
What is visible at night from the earth?
the stars and some of our planets
What percentage of visible stars are closer to the earth than the sun?
None are. The sun is the closest star to Earth. The next nearest star, Proxima Centauri, is about 260,000 times farther away than the sun is.
Are the same stars visible every night of the year from every location on earth?
No, the stars visible in the night sky change based on the Earth's rotation and its orbit around the Sun. The stars visible from a specific location depend on the time of year and the latitude of the observer. Some stars are circumpolar and are always visible in certain locations, while others may only be visible at certain times of the year.
Explain why stars appear to move across the sky each night why are some stars only visible doing certain seasons?
Stars appear to move across the sky each night because the earth is moving, but not the stars. Also some stars are only visible during certain seasons because as the earth rotates, they become visible.
Where on earth can you observe all the stars in the sky over an entire year?
Theoretically, you would need to be at the equator. However, from the equator you would never see the north star Polaris, because the haze of the atmosphere prevents you from seeing things within a degree or so of the horizon.
How many stars r in the sky?
Short answer: All of them are.More details:-- On the average, the faintest stars detectable by human eyes, in dark skiesduring conditions of good 'seeing', are those of the 6th magnitude.-- Roughly 5,000 stars exist with apparent visual magnitude at or below (brighter than) 6th magnitude.-- Depending on your location on Earth, the fraction of all stars visible to you at some timeduring the year varies from 50% (at the poles) to 100% (on the equator).-- At any moment during the night, the fraction of stars visible to you at any timethat are visible to you at that moment varies from 50% (at the equator) to 100%(at the poles).-- Averaging all the variables into a single number that may be equally inaccurateanywhere on Earth, you can assume that any time you're outside on a clear night,far from city lights and other sources of artificial illumination, during conditions of'good seeing', there are roughly 2,000 to 2,500 stars in the sky that are visible toyour unaided eyes.
