Distance to nearby stars can be determined from?
Distance to nearby stars can be determined using the method of trigonometric parallax, which involves measuring the apparent shift in position of a star relative to more distant stars as the Earth orbits the Sun. This shift allows astronomers to calculate the distance to the star based on the angle subtended by the Earth's orbit.
What happens to temperature as the angle at which the sun's rays strike the earth's surface increases. As the angle decreases. What happens to the length of the shadows at the same time?
As the angle at which the sun's rays strike the Earth's surface increases, the temperature tends to decrease. As the angle decreases, temperature tends to increase. At the same time, as the sun's angle decreases, shadows appear longer because the light is being cast at a greater angle.
At what angle will the sun's rays most directly hit the earth?
90 degrees
What determines the angle of a crescent moon?
The angle of a crescent moon is determined by the relative positions of the Sun, Earth, and Moon in space. It is a result of the sunlight reflecting off the Moon, with the angle changing as the Moon orbits the Earth and moves in relation to the Sun.
Which lunar phase would be observed from the Earth if the moon were at a 90 and deg angle with the earth and sun?
The New Moon
What is the maximum angle subtended on the celestial sphere by the separation of Venus and the sun?
Because Venus orbits closer to the Sun than the Earth, the angle between Venus and the Sun can never reach 180 degrees (the Sun and Venus cannot be directly opposite each other, or in "Opposition", as viewed from Earth). Assuming circular orbits for Earth and Venus of 149.6 million km and 108.2 million km respectively, and that the Earth and Venus orbit in the same plane, one can use trigonometry to find that the maximum angular separation between Venus and the Sun is approximately 46.3 degrees.
What does the angle of earth have to do with the seasons?
it affects the angle at which the sun rays hit the earth
What is a shadow angle?
an angle (that can be on the earth) at which an angle could be formed by the sun.
What is angle of insulation?
It is the angle at which the sun's rays hit the earth
What creates the season on earth?
The angle of the earth's tilt from the sun causes the Earth's seasons.
How does the angle of the sun hitting the earth affect the temperature of the earth?
Sunlight is at its strongest when it is at a perpendicular angle; at oblique angles it is weaker.
How are ratios used in astronomy?
The parsec is a unit of distance equivalent to about 3.26 light years or 31 trillion kilometres. It is used to measure the distances to stars, with kilo and mega parsecs being used for objects further away. A parsec is based on the tangent ratio. The angle in question is that subtended at the distant object by the lines joining it to the earth and the sun, and the opposite side is the earth-sun distance - 1 astronomical unit (AU). The result is the distance of the object from the sun.
How the placement of the sun's light on the earth causes seasons?
we get seasons because the earth is tilted on it s axis in relation to the sun thus as it goes around the sun the angle at which the light strikes the earth changes and the greater the angle the less heat is absorbed by the earth causing the seasons
What is the angle between the line from the earth to Jupiter and the line from earth to the sun when Jupiter is at opposition?
The angle between the line from Earth to Jupiter and the line from Earth to the Sun when Jupiter is at opposition is 180 degrees. This is because Jupiter, Earth, and the Sun are aligned in a straight line during opposition, with Earth in the middle.
How do changes in the angle of the sun's rays on the earth cause seasons in the northern hemisphere?
Changes in the angle of the sun's rays on the Earth cause seasons in the northern hemisphere because when the sun's rays hit the Earth at a more direct angle, it provides more concentrated heat and longer days, leading to warmer temperatures and summer. Conversely, when the sun's rays hit the Earth at a less direct angle, it diffuses the heat and results in colder temperatures and winter.
Why do the sun rays strike the earth's surface at different angles?
The angle at which the sun's rays strike the Earth's surface varies depending on the Earth's rotation and its position in relation to the sun. This angle changes throughout the day as the Earth rotates on its axis and as the Earth orbits around the sun, causing different parts of the Earth to receive sunlight at different angles.
Distance to nearby stars can be determined from?
Distance to nearby stars can be determined using the method of trigonometric parallax, which involves measuring the apparent shift in position of a star relative to more distant stars as the Earth orbits the Sun. This shift allows astronomers to calculate the distance to the star based on the angle subtended by the Earth's orbit.
