∙ 14y agoNeptune's average distance from the Earth = 4,564,000,000 km
4,564,000,000 ÷ 100,000 = 45,640 hours
45,640 hours = 1901 days and 16 hours
= 5 years, 76 days, and 16 hours

∙ 15y agoOn average, the distance between Earth and Neptune is about 4.3 billion kilometers. At a speed of 200,000 km/hr, it would take approximately 21,500 hours or about 2.5 years to travel from Earth to Neptune.

∙ 14y agoThe correct answer is that there's a lot more to it than just the speed of the spacecraft, and it takes an orbital physicist to come up with an answer. The reason is that spacecraft do NOT travel in straight lines. You and I, the planets, and the spacecraft, are all in orbits around the sun, and that doesn't change when we send a spacecraft to another planet. What we do with the rocket motors is only to tweak the spacecraft's solar orbit into a long elliptical orbit that intersects both the earth and the planet we want to hit. So the actual path winds up being a long, expanding curve.
But just to give you some kind of a feeling for the distances involved, let's assume that a spacecraft could travel a straight line from the earth's orbit to Neptune's orbit, and let's work out a number for the time required.
The average radius of the earth's orbit is 149.6 million km (93 million miles). The average radius of Neptune's orbit is 4.495 billion km (2.793 billion miles). So the average distance between the orbits is 4.345 billion km (2.700 billion miles).
You specified a speed of 200,000 km per hour (about 124,300 miles per hour).
The time required to cover the average distance between the orbits of earth and Neptune is
(4,345,000,000 / 200,000) = 21,727 hours = 59yrs + 192days. (approximate, rounded)
Again, this assumes a straight-line path from the earth to Neptune's orbit, which is NOT the route taken by spacecraft.

The closest distance of earth and neptune is 4.301 billion kilometers and the farthest distance of earth and neptune is 4.553 billion kilometers. So, the time to reach Neptune ranges from 8.602 hours to 9.106 hours.
No, there has not been any human travel to Neptune. Neptune is a gas giant located far from Earth, making it extremely difficult and costly to plan a mission to reach it. Robots and spacecraft have been sent to study Neptune, but not with the intention of manned travel.
No, as of now, there have been no manned or unmanned space flights to Neptune. The distance, challenges of sending a mission to such a distant planet, and technological limitations make it currently not feasible to send a spacecraft to Neptune.
Hubble has never "explored" Neptune. It is a telescope in orbit round Earth and from Earth it has "imaged" Neptune. It has done this several times eg 1996 and 1998 (there may be more times!).
The amount of time it takes for a space ship to travel toNeptune depends on where it is starting from, how much fuel it carries, how much acceleration can be applied and for how long, and what ath of travel (orbit) is followed.
Yes. The Earth travels in space as it goes around the Sun in it's annual orbit.
Light can travel through space. All the light that we get on the earth's surface; usually travels from the sun through space before it can reach here.
that depends on what kind of space travels you mean. frome 1. mill to al the earth resorses.

The International Space Station orbits the Earth in a west to east direction at a speed of approximately 28,000 kilometers per hour.
The closest distance of earth and neptune is 4.301 billion kilometers and the farthest distance of earth and neptune is 4.553 billion kilometers. So, the time to reach Neptune ranges from 8.602 hours to 9.106 hours.
Sound travels in waves like light or heat does, but unlike them, sound travels by making molecules vibrate. So, in order for sound to travel, there has to be something with molecules for it to travel through. On Earth, sound travels to your ears by vibrating air molecules. In deep space, the large empty areas between stars and planets, there are no molecules to vibrate. There is no sound there.
Light travels fastest through space, as it does not encounter any obstacles to slow it down. In other mediums, such as air, water, or glass, light will travel at a slower speed due to interactions with the medium's particles.
The space shuttle travels in the Earth's orbit, typically at an altitude of around 250 miles above the Earth's surface. It orbits the Earth at a speed of approximately 17,500 miles per hour, allowing it to counteract the pull of gravity and remain in orbit.
No, as of now, there have been no manned or unmanned space flights to Neptune. The distance, challenges of sending a mission to such a distant planet, and technological limitations make it currently not feasible to send a spacecraft to Neptune.
Light is a wave that travels through space across matter. The same way that waves travel from the center of a pond to the edges when you toss a stone in it.
A spacecraft or a rocket.
