How long does it take light to travel from the sun to Pluto?
It takes about 8 minutes for light to reach Earth and over FIVE hours for the same light beam to reach Pluto, the farthest known (dwarf) planet in our solar system. At its closest point to Earth, Pluto is about 4.38 billion kilometres away.
How does sunlight travel from the Sun to the Earth?
Electromagnetic WavesTo understand how light travels from the sun to the Earth, you have to understand what light is. Light is an electromagnetic wave–a wave of electric and magnetic energy oscillating very quickly. These electromagnetic waves travel in small packets called photons.
How much of the sun’s light reaches Earth?
All of the energy the sun releases does not reach Earth. One one-billionth of the Sun’s total energy output actually reaches the Earth. Of all the energy that does reach Earth, slightly less than 34 percent is reflected back to space by clouds. The Earth itself reflects another 66 percent back to space.

How long would it take to travel 1000 light years?
There are 6 trillion miles in a light-year (approximately), so the distance we need to go is 6 trillion miles / light-year times 4 light-years, or 24 trillion miles. So, this trip would take 1.2 billion hours. There are 24 hours a day and 365.25 days per year, so this time in years is 137 thousand years.
How old is the sunlight we see today?
between 10,000 and 170,000 years
Can we go to Sun?
On October 29, 2018, at about UTC, the spacecraft became the closest ever artificial object to the Sun. The previous record, 42.73 million kilometres (26.55×106 mi) from the Sun’s surface, was set by the Helios 2 spacecraft in April 1976.
How far does the sun reach?
150 million kilometers
Does the sun make noise?
The surface of the Sun produces sound waves because the surface is convecting and this produces pressure waves that travel into the inner corona. But yes, the surface does produce sound waves, but they have very low wavelengths measures in hundreds of miles!
What are 4 types of radiation from the sun?
Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.
Is the sun radioactive?
Definition of ‘radioactive’ according to Google: “emitting or relating to the emission of ionizing radiation or particles.” So, the sun emits ionizing particles, and is therefore radioactive. Most of what counts as radiation that you get is high energy UV due to black body radiation.
