“Earth: 0.00001582002493716235 light years, or about 8.3 light minutes away from the sun. Mars: 0.000024155306893301653 light years, or about 12.7 light minutes away from the sun. Jupiter: 0.00008233217279125351 light years, or about 43 light minutes away from the sun.”

How far away is each planet from Earth?

“Continue until you have marked off the distance to each planet (and dwarf planet, Pluto). 10….239,000 ÷ 36,373 = 6.57 hours.”

How long would it take to travel 1 light-year?

“Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.”

How many light minutes away is each planet from Earth?

“Mercury 0.387 193.0 seconds or 3.2 minutes Venus 0.723 360.0 seconds or 6.0 minutes Earth 1.000 499.0 seconds or 8.3 minutes Mars 1.523 759.9 seconds or 12.6 minutes Jupiter 5.203 2595.0 seconds or 43.2 minutes Saturn 9.538 4759.0 seconds or 79.3 minutes Uranus 19.819 9575.0 seconds or 159.6 minutes Neptune 30.058 …”

What is 1 light-year away from Earth?

“For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). That is a 6 with 12 zeros behind it!”

How many Earth like planets are in 50 light-years?

“Unknown Planets within 50 lightyears We know of over a thousand stars within fifty lightyears and expect that about 4,000 extrasolar planets orbit these stars. About a thousand roughly earth-sized planets are thought to be in the habitable zone.”

Which is the closest planet to Earth?

“Calculations and simulations confirm that on average, Mercury is the nearest planet to Earth—and to every other planet in the solar system.”

Which two planets are closest to Earth?

“Common sense would say the answer is either Mars or Venus, our next door neighbors. Of the two, Venus comes closer to the Earth than any other planet and its orbit is closest to ours. But as an article in Physics Today points out, over half the time Venus is not the nearest planet; Mercury is.”

Can we travel to Jupiter?

“While a spacecraft would have nowhere to land on Jupiter, it wouldn’t be able to fly through unscathed either. The extreme pressures and temperatures deep inside the planet crush, melt, and vaporize spacecraft trying to fly into the planet.”

Can a human travel a light-year?

“Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37,200 years to go one light-year.”

How fast speed of light is?

“Light from a stationary source travels at 300,000 km/sec (186,000 miles/sec).”

How far can we see in space?

“So the furthest out we can see is about 46.5 billion light years away, which is crazy, but it also means you can look back into the past and try to figure out how the universe formed, which again, is what cosmologists do.”

How many light-years is the Milky Way?

“Our galaxy probably contains 100 to 400 billion stars, and is about 100,000 light-years across.”

How is 1 hour in space equal to 7 years on Earth?

“How long is 1 hour in space in Earth years? The clocks in space tick more slowly than clocks on Earth., HENCE COVERING LESS TIME AS COMPARED TO EARTH IN THE SAME DURATION. One hour on Earth is 0.0026 seconds in space. Thus, upon calculation we find that one hour on Earth is equivalent to seven years in space.”

Do we see the Sun 8 minutes later?

“The Sun is about 150 million km away, so we see it as it was about 8 minutes ago. Even our nearest planetary neighbours, Venus and Mars, are tens of millions of kilometres away, so we see them as they were minutes ago.”

How many galaxies are there?

“The Hubble Deep Field, an extremely long exposure of a relatively empty part of the sky, provided evidence that there are about 125 billion (1.25×1011) galaxies in the observable universe.”

How big is the Milky Way?

““

How many light-years can we go?

“The light that travels the longest gets stretched by the greatest amount, and the object that emitted that light is now at a greater distance because the universe is expanding. We can see objects up to 46.1 billion light-years away precisely because of the expanding universe.”

How does NASA find planets light years away?

“While we cannot yet send spacecraft to planets beyond our solar system, scientists can study the light from exoplanets with telescopes. The telescopes they use to observe this light can be either in space, like the Hubble Space Telescope, or from the ground, like the Gemini Observatory telescopes.”

What planet is 1000 light years away?

“Wagg’s exoplanet is located in a distant solar system within our home galaxy, the Milky Way, 1,000 light years from Earth. It’s about the same size as Jupiter, but only takes two days to orbit its star. Jupiter, by comparison, takes 12 Earth years, or 4,272 days to orbit the sun.”

How many planets are in 10 light years?

“hosting Earth-type planets. As of October 2012, astronomers have been able to detect planets in the Solar System and around Alpha Centauri B and Lalande 21185 among the nearest 12 stars….Stars within 10 light-years.”

How long would it take to go 4.2 light years?

“Proxima Centauri is 4.2 light-years from Earth, a distance that would take about 6,300 years to travel using current technology. Such a trip would take many generations.”
