Gliese 581c is about 20 light years from Earth.
With present technology,
it would take many thousands of years to get there.
3-6. The 3 planet model would have gliese 581 b too hot, gliese 581 c in the habitable zone, and gliese 581 d too cold. The 6 planet model would have gliese 581 e, b, and c too hot, gliese 581 g and d in the habitable zone, and gliese 581 f too cold.
Gliese 581 is around 20.3 light years away from Earth. Traveling at the speed of light (approximately 186,282 miles per second), it would take about 20.3 years to reach Gliese 581. However, with our current technology, it would take significantly longer using conventional spacecraft.
A spaceship traveling from the moon to Earth at a typical speed of about 2.38 km/s would take approximately 3 days to cover the distance of about 384,400 km. The actual time may vary depending on the specific trajectory and speed of the spaceship.
The energy required for a spaceship to travel at 90 percent of the speed of light would be substantial due to the relativistic increase in kinetic energy as speed approaches the speed of light. The energy required can be calculated using Einstein's mass-energy equivalence formula, E=mc^2. The exact amount of energy would depend on the mass of the spaceship and would be calculated as the difference in energy between its rest mass and its kinetic energy at that speed.
The star Gliese 581 is a red dwarf star, 20.3 light-years away. Recent observations indicate that a number of planets orbit this star, including at least one of approximately Earth's mass that astronomers say may be within the habitable zone, meaning that the temperature of the planet's surface may - MAY - allow water to exist in a liquid state. It's important to remember that much of the speculation about Gliese 581g is EXTREMELY speculative. We don't know what sort of surface the planet might have, nor anything about the atmosphere; the ONLY things we know even approximately are the mass and the orbit. At a first glance, it might seem like this could be a potentially habitable world - but notice all of the weasel-words that I used. We don't have ANY idea of the conditions there.
If I went to travel in a spaceship, I would take a lot of pictures.
3-6. The 3 planet model would have gliese 581 b too hot, gliese 581 c in the habitable zone, and gliese 581 d too cold. The 6 planet model would have gliese 581 e, b, and c too hot, gliese 581 g and d in the habitable zone, and gliese 581 f too cold.
It will take me 20+ years since i can walk at the speed of light!;p Wait a minute, i get my hyperspace technology fixed and i will be there in a few minutes.. You guys are slow... it will take u guys 85,000+ years to get there!! In otherwards, you can't!
A spaceship.
A spaceship.
If it is a rocky planet with a large iron core, Gliese 581c has a radius approximately 50% larger than that of Earth. Gravity on such a planet's surface would be approximately 2.24 times as strong as on Earth. If Gliese 581 c is an icy and/or watery planet, its radius would be less than 2 times that of Earth, even with a very large outer hydrosphere. Gravity on the surface of such an icy and/or watery planet would be at least 1.25 times as strong as on Earth.
Everyone would go there by spaceship for the parties !!
You can travel in a spaceship. But you would have to be really well protected from the sun radiation and obviously have a way of reusing water and have enough food for the trip as it would take months to get there and back. The problem with the planet mercury is that it is so close to the sun that the temperatures would be very high.
Ten seconds.
That would be the Moon. Yes, our Moon. Space 1999 used it to travel the stars.
A spaceship can 'fall' from the sky if it loses power , fails to maintain orbital velocity , loss of ship's controls and/or the ship is caught by the gravitational field of the planet , etc . . .
We don't know where the farthest planet is. But if we assume it's at the edge of the observable universe, then it depends on how fast we go:A spaceship travelling as fast as we can go in 2017 would take 838 trillion years.A spaceship travelling at the speed of light (which is virtually impossible) would take 45 billion years.A star trek Starship travelling at variable warp speeds would take about 45 million years
