Jupiter
| Spacecraft | Launch Date | Carrier rocket |
|---|---|---|
| Voyager 1 | 5 September 1977 | Titan IIIE Centaur-D1T |
| Galileo | 18 October 1989 | Space Shuttle Atlantis STS-34 / IUS |

| Cassini–Huygens | 15 October 1997 | Titan IV(401)B Centaur-T |
How fast can we travel a light year?
This duration is a bit of a problem, as it makes space exploration a painstakingly slow process. Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37,200 years to go one light-year.
Are we in contact with voyager1?
Even though Voyager 1 and 2 are now 43 years old and farther from Earth than any other operating spacecraft in history, however, they’re not lost to us yet. The key is through NASA’s Deep Space Network: a collection of radio antennae designed to communicate with humanity’s most distant spacecraft.
Where is Oumuamua now?
‘Oumuamua is currently moving away from Earth at nearly twice the speed of Voyager 1, the fastest spacecraft ever built. The asteroid travels about 500 million miles per year—the average distance between the Earth and Jupiter—which means it will enter interstellar space sometime in the late 2030s.
Why is Oumuamua not an asteroid?
As the first known object of its type, ʻOumuamua presented a unique case for the International Astronomical Union, which assigns designations for astronomical objects. Originally classified as comet C/2017 U1, it was later reclassified as asteroid A/2017 U1 due to the absence of a coma.
Is there an asteroid coming in June 2020?
A huge asteroid, 2020 KN5,will safely fly past the earth over a pace of 28,000 miles per hour on Thursday, June 4, 2020. Due to the Earth-intersecting orbit, it has been classified as an Apollo asteroid.
Did Oumuamua speed up?
Oumuamua has sped up In fact, it passed the orbit of Jupiter earlier than predicted, indicating it accelerated along its trajectory. Oumuamua was approximately 100,000 km farther than could be explained based on purely gravitational interactions.
What does Oumuamua mean in Hawaiian?
Today Oumuamua, the Hawaiian term for “scout,” as the object was named, is now long gone, somewhere between the orbits of Saturn and Neptune and on its way to the Great Out There, but astronomers are still wondering and debating what it was.
Are there pictures of Oumuamua?
We do not have a photo of ‘Oumuamua, but its brightness owing to reflected sunlight varied by a factor of 10 as it rotated periodically every eight hours.
Is Comet Atlas visible?
C/2019 Y4 (ATLAS) (or Comet ATLAS) is a comet with a near-parabolic orbit discovered by the ATLAS survey on December 28, 2019. The comet continues to fade and did not reach naked eye visibility. By mid-May, comet ATLAS appeared very diffuse even in a telescope. C/2019 Y4 (ATLAS) has not been seen since May 21, 2020.
Where can I find Comet Atlas in the night sky?
Right now, ATLAS can be viewed by a medium-sized telescope. But as it gets closer to the Sun, and increases in brightness, then observers can ditch the equipment and opt for a portable pair of binoculars instead. If it does reach the predicted brightness peak, then it could be seen by the naked eye.
Where can I find Comet Swan?
Look at the night sky just before dawn or a little after sunset for the next couple of weeks and you could see a comet with a hint of green streaking across the sky. That’s the Comet SWAN. Space.com’s Joe Rao says SWAN will track north and east between the constellation Triangulum and Auriga.
Is Neowise still visible 2021?
This comet will be initially visible from the Northern Hemisphere, and will become visible from the Southern Hemisphere in December 2021 and January 2022.
