Is the Sun 1 lightyear away from Earth?

1 Light year is the time Light takes to travel in one year. From the Photosphere of the Sun, light only takes 8.3 minutes to reach the Earth, this means that the Sun is only 8.3 light minutes away from Earth or 1.5781e-5 Light years. 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. At this speed, how many days would it take to travel to the sun from Earth, located at a distance of 149 million kilometers? Answer: Time = Distance/speed so Time = 149,000,000 km/ 28,000 = 5321 hours or 222 days. Since light travels at about 186,300 miles per second, with 86,400 seconds per day and about 365 days per year, that works out at about: 186300×86400×365≈5,875,000,000,000 miles. 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.

What if the sun vanished for 1 second?

Eternal night would fall over the planet and Earth will start traveling into interstellar space at 18 miles per second. Within 2 seconds, the full moon reflecting the sun’s rays on the dark side of the planet would also go dark. Re: How would you age at the speed of light The simple answer is, anything moving through space at c, equal to the speed of light in a vacuum, experiences zero time flow. If you were to travel at the speed of light, you would experience no time. You might think it would suddenly become very cold. But it wouldn’t. You wouldn’t even notice the difference. Our planet has stored enough heat in its atmosphere and oceans to keep us warm for those five seconds without the Sun. If the sun would go out, no life could survive on most of earth’s surface within a few weeks. Water and air would freeze over into sheets of ice. Because the black hole is about 27,000 light-years away from Earth, it appears to us to have about the same size in the sky as a donut on the Moon.

Is traveling a light-year possible?

Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. According to Albert Einstein’s theory of special relativity, summarized by the famous equation E=mc2, the speed of light (c) is something like a cosmic speed limit that cannot be surpassed. So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. So, according to de Rham, the only thing capable of traveling faster than the speed of light is, somewhat paradoxically, light itself, though only when not in the vacuum of space. Of note, regardless of the medium, light will never exceed its maximum speed of 186,282 miles per second. Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, traversable wormholes, and Alcubierre drives.

How hot is the sun?

How long will it take to get to Mars?

The spacecraft departs Earth at a speed of about 24,600 mph (about 39,600 kph). The trip to Mars will take about seven months and about 300 million miles (480 million kilometers). Starting from launch on January 19, 2006, and with a gravity assist from Jupiter along the way, NASA’s New Horizons spacecraft took 9 years and 5 months to get to Pluto, 39 AU from the Sun. It traveled at an average speed of 4.1 AU/year. On an average jet plane, flying at 550 miles per hour, it would take 19.29 years, or 7,045 days to travel the 93 million miles to the Sun. Light travels at a speed of 299,792 kilometers per second; 186,287 miles per second. It takes 499.0 seconds for light to travel from the Sun to the Earth, a distance called 1 Astronomical Unit.
