Is Mercury closer to the sun than Earth?
Yes, Mercury is closer to the sun than Earth.
Why does the moon appear the same size as the sun during a total solar eclipse?
During a total solar eclipse, the moon appears the same size as the sun because of a coincidence in their relative distances and sizes. The moon is about 400 times smaller than the sun, but it is also about 400 times closer to Earth than the sun. This alignment causes the moon to perfectly cover the sun, creating the illusion that they are the same size in the sky.
Why is the sun so orange?
The sun appears orange during sunrise and sunset due to the Earth's atmosphere scattering shorter wavelengths of light, such as blue and green, while allowing longer wavelengths, like red and orange, to pass through. This scattering effect causes the sun to appear orange or red when it is closer to the horizon.
What is the period of rotation of the sun about its own axis?
Around the equator the Sun rotates once every 24.47 days. However this number changes with latitude, because the Sun experiences what astronomers call differential rotation. This is because the Sun is not solid like the Earth but gaseous. At the poles the rotation period is longer, about 33.5 days.
Why is it sunny in winter but not warm?
In winter, the angle of the sun is lower in the sky, which reduces the amount of heat reaching the Earth's surface even though the sun may be shining brightly. Additionally, during winter, the Earth's surface is tilted away from the sun in the Northern Hemisphere, leading to cooler temperatures despite the sunny weather.
The vernal and autumnal equinoxes where is the sun in relation to the equator during?
At the Equinoxes, the Sun is directly above the equator.
What line of latitude receives the sun's direct rays during the equinoxes?
The equator is the line of latitude that receives the sun's direct rays during the equinoxes. This is because the Earth's axis is tilted neither toward nor away from the sun during the equinoxes, causing the sun's rays to strike the equator perpendicularly.
Where does the noon sun fall during both equinoxes?
During the equinoxes, when the Sun is at its highest, it will be at a distance from the zenith which is the same as your geographical latitude, but in the opposite direction. For example, if you live 50 degrees north of the equator, the Sun will be 50 degrees south of the zenith at noon.
The sun is most directly overhead near the what?
The sun is most directly overhead near the equator. This happens during the equinoxes where the sun is directly above the equator, resulting in near-vertical rays at noon.
The places the Sun crosses the equator are called the?
The places where the Sun crosses the equator are called the equinoxes. There are two equinoxes each year: the vernal (spring) equinox in March and the autumnal equinox in September. During these times, day and night are approximately equal in length all over the world.
When on a equator day will the overhead the earth at midday?
If you are at the equator, the SUN will be directly overhead during the equinoxes - around 21 March, and 23 September.
Is the sun directly overhead in the equator?
Not always. The sun is directly overhead at the equator at the spring and fall equinoxes.
The sun is on the celestial equator at the times of the?
The equinoxes are the two points on the celestial equator there the ecliptic(the sun's apparent annual path through the stars) crosses it.Note that the equinoxes are not events or dates. They are points on the mapof the stars.
Where are the sun's direct rays on the equinoxes?
On the equinoxes, the sun's direct rays fall on the equator. This causes day and night to be of equal length all over the world.
The vertical ray of the sun strikes the earth where?
The vertical ray of the sun strikes the Earth directly at the equator. This phenomenon occurs during the equinoxes when the sun is directly above the equator, causing equal day and night lengths at all locations on Earth.
The sun is most directly overhead near the?
The sun is most directly overhead near the equator, around the Tropic of Cancer and the Tropic of Capricorn. This occurs during the two equinoxes in March and September.
When is the sun vertically overhead of the Equator?
The sun is vertically overhead at the Equator during the equinoxes, which occur around March 20-21 and September 22-23 each year. During these times, the sun's rays are directly perpendicular to the Equator, resulting in nearly equal day and night lengths across the globe.
