What is a fraction of the sun's diameter?
The diameter of the sun is approximately 1.4 million kilometers. If we want to express a fraction of the sun's diameter, we would need to specify the numerator (the part we are interested in) and the denominator (the total diameter of the sun). For example, if we were interested in one-tenth of the sun's diameter, the fraction would be 1/10, which would equate to 140,000 kilometers.
Why did people think that Copernicus was wrong?
Everyone thought that the sun orbits the Earth and all other planets but Copernicus studied the ski carefully. He found out that the Earth and all other Planets orbits the sun and the earth is not the centre of the universe. The sun is.
Does the sun turn off?
The answer is no its on every day but the earth rotates and wherever the the sun is shining that the place theres sun
How many miles is earth away from the sun in scientific notation?
The earth is 92,960,000-miles away from the sun. In scientific notation that is 1.496 X 108 km. The sun is the star at the center of our solar system.
What are some of Copernicus' discoveries and contributions?
he discovered that the earth revolved around the sun (heliocentricity) and at that time everyone believed that the sun/planets revolved around the earth (geocentricity)
How much of the total surface of the Moon is illuminated by the Sun when it is at quarter phase?
At quarter phase, half of the Moon's surface is illuminated by the Sun. However, from our perspective on Earth, we see only half of that illuminated portion, which is one quarter of the total surface.
How much of the Moon's surface is illuminated by the sun at any time regardless of how much of that light can be seen from earth?
At any given time, one half of the Moon's surface is illuminated by the sun, just like on Earth. The portion of the Moon's illuminated side that we can see from Earth depends on its position in its orbit around our planet.
What is the efffect of rotation of the earth when facing the sun?
The illuminated patch on the earth's surface drifts westward relative to a fixed point on the earth as the earth spins eastward.
Why is the moon illuminated?
The moon is illuminated because it reflects light from the Sun. This phenomenon is visible to us on Earth depending on the position of the moon in relation to the Sun and the Earth. Different phases of the moon result from how much of the illuminated side we can see from Earth.
How much of the entire moon's surface is illuminated by the sun at first quarter?
At any time, half of the entire Moon's surface is illuminated.
What portion of earth receives energy form the sun at any given time?
Since the Earth is a Spheroid shape, (not a true sphere) 50% of its surface is illuminated by the Sun, at any given moment.
What fraction of the moon do we see during a quarter moon?
During a quarter moon, we see half of the moon's surface lit up by the sun. This is because the angle between the sun, Earth, and moon creates a line where we see only half of the illuminated side.
How much of the moon is always lit up by the sun?
Roughly half of the moon is always illuminated by the sun. This is because the moon orbits Earth and as it does so, different portions of its surface receive sunlight, leading to different lunar phases.
How much of the moon is illuminated by the sun at each position as the Moon's orbits earth?
Half (50 percent) of the moon is illuminated by the sun at all times, just as half of earth is always illuminated.The thing that changes is: How much of the moon's illuminated half can we see from earth ?
How can you see the moon at night?
It is illuminated by the Sun, just as Earth is.
Is the earth luminous?
The Earth itself is not luminous. It reflects sunlight that hits its surface, which gives it the appearance of being illuminated. The Earth does not generate its own light like the sun or other luminous objects.
Is the moon always dark on one side?
No, the moon does not have a permanent dark side. It goes through phases where different portions of its surface are illuminated by the sun, so all sides of the moon experience day and night over the course of a lunar cycle.
