Not all light that reaches the Earth is 2.5 million years old. Light produced from a star that is 2.5 million light years away reaches Earth in 2.5 million years. Light from the sun, for example, is only 8 minutes old. Light that is reflected from the surface of the moon takes about 1.28 seconds to reach Earth.
What else can I help you with?
The sun is 1 light year away from the earth?
Wrong!!!!! The Sun is 1 A.U. ( Astronomic Unit) from Earth. Because of the immensity of space, distances are calculated in 'A.U.' or 'Light Years'. Photons of Light from the Sun takes approximately 8 minutes to reach Earth.
What is the distance in light years of the sun to earth?
Less than 1 light year. Lots less. It's not a light year away, it's 8.333 light minutes away . Light travels about 5.9 trillion miles in a year, and the sun is only 93 million miles away. The speed of light is 186,000 miles/second, so light from the sun reaches the earth in 500 seconds, or 8 minutes and 20 seconds. So, the sun is about 0.0000158 light years from the earth.
Is a light year 150 million km?
No. 150 million km is the distance from Earth to Sun, and this distance is called an AU (astronomical unit). Light travels this distance in about 8 minutes.A light-year is the distance traveled by light in a year, which of course is much more than the distance traveled in 8 minutes. A light-year is approximately 9.461 x 10 to the power 12 km.
What is larger a astronomical unit or light year?
A light year is larger than an astronomical unit. One astronomical unit (AU) is the average distance between the Earth and the Sun, approximately 93 million miles. A light year is the distance that light travels in one year, which is about 5.88 trillion miles.
How far away is earth from the Andromeda galaxy in kilometers in scientific notation?
The Great Galaxy in Andromeda (also known as the Andromeda Galaxy or M31) is about 2.5 million light years from Earth. When we look at this galaxy today, we see light that has been traveling through space for 2.5 million years; i.e. when we look at the Andromeda Galaxy, we are seeing it as it was about 2.5 million years ago! Think about this, we are looking back in time.1 light year is the distance that light travels in 1 year. Speed of light is 300,000 kilometers/second, find the distance that light travels from the Andromeda Galaxy to Earth in kilometers and express it in scientific notation.
Is 1 light year equal to 150 million years?
No, 150 million years is an amount of time. A light-year is a distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km).
If you are 11 years old now how old will you be when light that is leaving today reaches earth?
One light-year is about 9 trillion kilometers.Arcturus is a star that is 37 light-years from Earth.
What is the light year of Venus's?
A light year is a distance, or the total distance a ray of light can travel in 1 year (light travels at 300,000,000m per second) to be accurate. When Venus is closest to earth, it is about 38 million kilometres away (0.000004017 light years). When Venus is furthest from earth, it is about 261 million kilometres away (0.000027588 light years).
What date does the earth get closest (148 million km) to the sun?
The Earth reaches its closest point to the Sun, known as perihelion, around January 3 each year. At this time, the distance between the Earth and the Sun is approximately 147 million kilometers (about 91 million miles). This event is part of Earth’s elliptical orbit and varies slightly each year.
How far is the NGC 6166 from Earth?
It is about 490 million light years away. A light year is a measure of distance, based on light travelling about 9.4 trillion kilometres in a year or about 5.9 trillion miles in a year.
How far is 36 light years into km?
Each light-year is approximately 10 million million kilometers, or 1013 km.Each light-year is approximately 10 million million kilometers, or 1013 km.Each light-year is approximately 10 million million kilometers, or 1013 km.Each light-year is approximately 10 million million kilometers, or 1013 km.
The sun is 1 light year away from the earth?
Wrong!!!!! The Sun is 1 A.U. ( Astronomic Unit) from Earth. Because of the immensity of space, distances are calculated in 'A.U.' or 'Light Years'. Photons of Light from the Sun takes approximately 8 minutes to reach Earth.
What would happen if Earth had a highly elliptical orbit when it gets as far as a light year from the sun and as close at a million miles from the sun?
If Earth had such an extreme elliptical orbit, it would face significant challenges for sustaining life. At a million miles from the sun, the planet would suffer from extreme heat, potentially leading to the evaporation of oceans and the destruction of the atmosphere. Conversely, at a light year from the sun, Earth would freeze due to lack of solar radiation, making it uninhabitable.
How many days does the earth have light?
the earth has light every day except in Alaska it has 205 days every year now if you talkin about how many days the earth has light left we in all facts we have about 100 million years left

Earth travels around the sun in light years?
how many light years the earth travels around the sunNo. The Earth travels around the Sun in a measurement of time called a year, which is one revolution or trip around the sun: approximately 584,020,178 miles.A light year is a measurement of distance that light travels in one year, which is approximately 5.88 Trillion (5,880,000,000,000) miles!
Does a meteor reaches the earth?
Yes, thousands do every year.
