How many light years does it take to get to Mercury from Earth?
How many light years does it take to get to Mercury from Earth?
“At its average distance of 36 million miles, light takes 3.21 minutes to reach Mercury from Earth.”
How many light seconds away is Mercury?
“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 …”
How far is Mercury from Earth today?
“The distance of Mercury from Earth is currently 100,484,283 kilometers, equivalent to 0.671696 Astronomical Units.”
Why does it take 7 years to get to Mercury?
“According to Kepler’s third law of planetary motion, Mercury whizzes around the Sun on its tight orbit much quicker than Earth. So, our spacecraft heading to Mercury will have to gain some speed to catch up with the tiny planet.”
Which is older Earth or Mercury?
“Mercury is exactly the same age as all the rest of the planets in the Solar System: approximately 4.6 billion years old. Astronomers think that our entire Solar System started out as a giant cloud of cold molecular hydrogen gas, left over from the Big Bang 13.7 billion years ago.”
How far is one 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.”
What is 1 light second away?
“The light-second is a unit of length useful in astronomy, telecommunications and relativistic physics. It is defined as the distance that light travels in free space in one second, and is equal to exactly 299792458 metres (983571056 ft).”
How far is one light day?
“A light day is an astronomical unit of length. It is defined as the distance light travels in an absolute vacuum in one day (of 86,400 seconds) or 25,902,068,371,200 meters (~26 Tm).”
How long is 1 second in space?
“1 second in space is equal to 1 second in earth. Space time doesn’t move any faster than earth time so we use earth time for all of outer space.”
Can humans walk on Mercury?
“Could humans land on Mercury’s surface? In spite of being so close to the Sun, and wild swings in extreme temperatures, humans could technically walk on the planet’s surface. Mercury’s slow rotation means it takes 59 Earth days for it to turn around once.”
Can humans live Mercury?
“It is unlikely that life as we know it could survive on Mercury due to solar radiation, and extreme temperatures.”
Has a human ever landed on Mercury?
“No, Mercury has been visited by spacecraft from Earth, but no human has ever gone into orbit around Mercury, let alone stepped on the surface.”
How long can a human live in Mercury?
“At its current rotational velocity, it takes about 176 Earth days to experience one Mercurian day-night cycle. But you wouldn’t make it to the next day because you would die in about two minutes due to freezing or burning up.”
Can we land on Venus?
“Yes, several landers from the former Soviet Union have landed on Venus. They were only able to send us information for a short time because the extremely high temperature and pressure on the surface of Venus melted and crushed the landers.”
Why is life impossible in Mercury?
“Scientists do not believe there has ever been life on Mercury. The atmosphere on Mercury is almost non-existant. It doesn’t protect the planet from the harsh radiation of the Sun or radiation from space, nor does it trap heat and provide a breathable atmosphere. Mercury is inhospitable and sterile.”
Who is the oldest planet?
“Jupiter formed less than 3 million years after the birth of the solar system, making it the eldest planet. Saturn formed shortly after, amassing less material since Jupiter gobbled such a large portion of the outer disk.”
What is the oldest known planet?
“The planet is one of the oldest known extrasolar planets, believed to be about 12.7 billion years old….PSR B1620−26 b.”

What is the oldest thing Earth?
“SEA FOREST: Approximately 200,000 years. A sprawling sea grass meadow ten miles long near Spain ranks as the oldest known single organism on Earth, according to geneticists. Posidonia oceanica, known as Neptune’s grass, is endemic to the Mediterranean Sea.”
How long does light take to get to Mercury?
“From an average distance of 36 million miles (58 million kilometers), Mercury is 0.4 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. From this distance, it takes sunlight 3.2 minutes to travel from the Sun to Mercury.”
How far away is Voyager 2 in light-years?
“Our galaxy is 100,000 light-years across, and Voyager 2 is now just under 18 light-hours away from Earth.”
How long will Voyager 1 last?
“How long can Voyager 1 and 2 continue to function? Voyager 1 is expected to keep its current suite of science instruments on through 2021. Voyager 2 is expected to keep its current suite of science instruments on through 2020. The radioisotope thermoelectric generator on each spacecraft puts out 4 watts less each year.”
