Therefore, a light shining from the surface of Mars would take the following amount of time to reach Earth (or vice versa): Closest possible approach: 182 seconds, or 3.03 minutes. Closest recorded approach: 187 seconds, or 3.11 minutes.

The total journey time from Earth to Mars takes between 150-300 days depending on the speed of the launch, the alignment of Earth and Mars, and the length of the journey the spacecraft takes to reach its target.

Last year, astronomers raised the possibility that our nearest neighbor, Proxima Centauri, has several potentially habitable exoplanets that could fit the bill. Proxima Centauri is 4.2 light-years from Earth, a distance that would take about 6,300 years to travel using current technology.

Mars is a planet with a very similar daily cycle as the Earth. Its sidereal day is 24 hours, 37 minutes and 22 seconds and its solar day 24 hours, 39 minutes and 35 seconds. A Martian day (referred to as “sol”) is therefore approximately 40 minutes longer than a day on Earth.

The planet is about 1,400 light-years away from the Solar System. At the speed of the New Horizons spacecraft, about 59,000 km/h (37,000 mph), it would take approximately 26 million years to get there.

At their closest, Earth and Mars are 225 million kilometers apart, which is equal to 12.5 light minutes, making the journey from Earth to Mars, if a straight line course was possible, twelve and a half minutes at Warp 1.

And we're talking 100,000 trips of a giant spaceship. The notional journeys outlined in the November 2016 talk would require 80 to 150 days of transit time, with an average trip time to Mars of approximately 115 days (for the nine synodic periods occurring between 2020 and 2037).

It takes about 3 days for a spacecraft to reach the Moon. During that time a spacecraft travels at least 240,000 miles (386,400 kilometers) which is the distance between Earth and the Moon.

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.

While Earth takes precisely 23h 56m and 4 s to complete a single sidereal rotation (0.997 Earth days), Mars does the same in about 24 hours and 40 minutes. This means that one Martian day (aka. Sol) is very close to single day on Earth.

Therefore, the amount of time it would take to get to Jupiter really depends on how fast you are going, the path you take in space, and where the planets are located in their orbits. Travel to Jupiter can be anywhere between just over 13 months to eight years.

The speed of light Light travels at approximately 186,282 miles per second (299,792 km per second). Therefore, a light shining from the surface of Mars would take the following amount of time to reach Earth (or vice versa): Closest possible approach: 182 seconds, or 3.03 minutes.

See NASA's big plans for its new Mars rover, Perseverance (CNN) The NASA Perseverance rover has been confirmed to be healthy and is now on a journey to Mars. It will take between 6.5 and seven months before the rover lands on the red planet in February 2021.

How long does it take to travel to Mars? The trip takes around seven months; a bit longer than astronauts currently stay on the International Space Station.

Voyager 1, Earth's most distant spacecraft, left the solar system and entered interstellar space in 2012. According to NASA, it is currently speeding away at 38,200 mph. For Voyager 1 to travel 39 light-years, it would take the spacecraft 685,000 years. But Voyager 1 isn't going there anytime soon, or ever.

Many space agencies have taken advantage of this orbital alignment and sent many spacecraft to Mars. The journey usually takes between 150 to 300 days, depending on the speed of the launch, the alignment, and the length of the trip.

This sounds like a strange question, but think about it. Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.
