Voyager 2
Would it be possible to travel to Neptune?
Neptune has been directly explored by one space probe, Voyager 2, in 1989. As of January 2022,
there are no confirmed future missions to visit the Neptunian system
, although a tentative Chinese mission has been planned for launch in 2024.
Where is Voyager 1 now?
NASA’s Voyager 1 spacecraft is currently
over 14.1 billion miles from Earth
. It’s moving at a speed of approximately 38,000 miles per hour and not long ago passed through our solar system’s boundary with interstellar space.
Does it rain diamonds in Neptune?
Deep within Neptune and Uranus, it rains diamonds
—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.
What would happen to a human if they traveled to Neptune?
If a person were to attempt to stand on Neptune,
they would sink through the gaseous layers
. As they descended, they would experience increased temperatures and pressures until they finally touched down on the solid core itself.
How much would a 100 pound person weigh on Neptune?
The surface gravity on Neptune is about 110% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh
110 pounds
on Neptune (assuming you could find someplace to, well, stand).
Has any human been to Mercury?
Have astronauts from Earth ever stepped foot 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.
Will Voyager 1 leave the Milky Way?
Will Voyager 1 ever stop?
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.
How long is a year on Mars?
687 days
What planet rains fire?
Last year, astronomers revealed the “
hot Jupiter
,” which lies about 640 light-years from Earth, has a curious nighttime quirk. Every evening on the planet it rains iron.
What would happen if you fell into Uranus?
Why is Neptune blue?
The predominant blue color of the planet is
a result of the absorption of red and infrared light by Neptune’s methane atmosphere
. Clouds elevated above most of the methane absorption appear white, while the very highest clouds tend to be yellow-red as seen in the bright feature at the top of the right-hand image.
Why can’t humans live on Uranus?
Uranus’ environment is not conducive to life as we know it.
The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to
.
Can we live on Pluto?
The surface of Pluto is extremely cold, so
it seems unlikely that life could exist there
. At such cold temperatures, water, which is vital for life as we know it, is essentially rock-like.
Is Neptune suitable for life?
Lifeless.
Neptune cannot support life as we know it
.
How much would I way on Pluto?
The surface gravity on Pluto is about
1/12th the surface gravity on Earth
. For example, if you weigh 100 pounds on Earth, you would weigh 8 pounds on Pluto.
How old would I be if I lived on Mars?
(45 years x 365 days on earth) Mars has longer years than Earth. So on Mars, I would only be
23.9 years old
. (16,425 earth days divided by the 687 days in a Mars years) So I would be younger on Mars, but possibly still look the same way that I look on Earth.
What is Earth’s gravity?
9.807 m/s2
Has anyone been to the Sun?
No. Outside mythology, no human has ever attempted to travel to the Sun
. The main reason is fairly obvious—it’s too hot. Even in a well-protected spacecraft, you could only get within about 2 million kilometres (1,300,000 mi) before burning up.
Can we visit Uranus?
Only one spacecraft has visited distant Uranus
. After traveling more than 1.8 billion miles (3 billion kilometers) in nine years, NASA’s Voyager 2 gathered much of its critical information about the mysterious planet, including its rings and moons, in just six hours.
Has anyone been to Jupiter?
Mankind has been studying Jupiter for more than 400 years. But we’ve only been sending spacecraft there since the 1970s!
Nine spacecraft have visited Jupiter since 1973
, and they’ve discovered a lot about the planet.
How far will Voyager 1 be in a billion years?
The Voyagers have enough electrical power and thruster fuel to keep its current suite of science instruments on until at least 2025. By that time, Voyager 1 will be about
13.8 billion miles
(22.1 billion kilometers) from the Sun and Voyager 2 will be 11.4 billion miles (18.4 billion kilometers) away.
Has anything ever left the Milky Way?
Voyager 1 Becomes First Man-Made Object to Leave Solar System
; Probe Still Powered by GE Technology. A new research paper published today in the journal Science concluded that the Voyager 1 spacecraft became the first man-made object to leave the solar system and enter interstellar space.
How much fuel does Voyager 1 have left?
NASA estimates that the Voyagers’ fuel efficiency is
upwards of 30,000 miles per gallon of hydrazine
. Voyager 1 has enough hydrazine to keep going until 2040, while Voyager 2’s juice can keep it hurtling along until 2034.
