- Neptune, the most distant planet, takes 4.16 hours for light to reach. The nearest star, Proxima Centauri, takes light 4.3 years to get to. The fastest spacecraft ever launched from Earth is NASA's New Horizons mission, which will make a close encounter with Pluto and its moons in 2015.

Do I Know This ? Neptune, the Farthest Planet from the Sun. Neptune is the eighth planet from the sun. Now that Pluto is no longer regarded as a true planet, Neptune is the farthest planet from the sun. Only one spacecraft has ever visited this planet in a flyby because it would be impossible to land on its non-solid surface.It captured photos and information.t is 30 times farther from the sun than the earth is. In fact, only 1/900 of the sun’s energy that reaches the earth ever reaches Neptune. When Voyager 2 was sent on a mission to explore it, it took 12 years for it to reach the planet. It takes 165 earth years for Neptune to complete a single orbit around the sun.

Table of Contents Nearly 4.5 billion kilometers (3 billion miles) from the Sun, Neptune orbits the Sun once in 165 years, and therefore has made not quite a full circle around the Sun since it was discovered. With an equatorial diameter of 49,528 kilometers (30,775 miles), Neptune is the smallest of our solar system's gas giants.n the summer of 1989, NASA's Voyager 2 became the first spacecraft to observe the planet Neptune, its final planetary target. Passing about 4,950 kilometers (3,000 miles) above Neptune's north pole, Voyager 2 made its closest approach to any planet since leaving Earth 12 years earlier.

Neptune Neptune orbits the Sun once every 164.8 years at an average distance of 30.1 astronomical units (4.50×109 km). It is named after the Roman god of the sea and has the astronomical symbol ♆, a stylised version of the god Neptune's trident.

How long does it take to get to Neptune? Best Answer: The minimum distance from Earth to Neptune is 4.3 billion km or 2.68 billion miles. I think the first answerer made a calculation error. With the speed of sound being 1230 kilometers per hour (343 m/s), I get 33.88 years to Neptune at the speed of sound.

How long would it take light from the sun to reach pluto? please tell me how u found it show your work.? (Max) Distance from sun to pluto ~7 trillion meters speed of light ~299,792,458 meters per second divide the distance by the speed of light to get time ~23349.5 seconds ~389 minutes ~6.5 hours. Average distance to Pluto is 5,900^6 km Speed of light is 1,079,252,849 km/hour 5,900^6 ÷ 1,079,252,849 = 5.567 hours.

Orbit and Rotation of Neptune As a result, Neptune would often experience seasonal changes that are similar to ours. However, the planet’s long orbital pretty much means that the seasons last for about forty Earth years at a time. Its sidereal rotation or day lasts for about 16.11 hours; a day on Neptune is equivalent to 16.11 Earth hours. Because of the fact that its axial tilt is similar to that of the Earth’s the variations in the length of its days don’t get any more extreme.

How Long Does It Take to Get to Pluto? At its most distant point, known as “aphelion”, Pluto reaches a distance of 7.3 billion kilometers, or 49 AU. This will happen on August 23, 2113. I know, these numbers seem incomprehensible and lose their meaning. So let me give you some context. Light itself takes 4.6 hours to travel from the Earth to Pluto. If you wanted to send a signal to Pluto, it would take 4.6 hours for your transmission to reach Pluto, and then an additional 4.6 hours for their message to return to us. Let’s talk spacecraft. When New Horizons blasted off from Earth, it was going 58,000 km/h.

How many light-years away is Neptune from Earth? Since 1 light year is 9,460,730,472,580.8 km, Neptune will be 0.0004546 of a light year away. This is the closest possible. Secondly, Earth is at aphelion and Neptune is at aphelion but in conjunction-diametrically opposite the Earth on the other side of the Sun. In this case the separation will be 4,553,946,490 km + 152,097,701 km or 4,706,044,191 km. This is 0.0004974 of a light year, the furthest possible.

How long does it take Neptune to rotate on its own axis? Answers. Best Answer: The sidereal (sr) rotation period is 16 hours, 6 minutes and 36 seconds. That's how long it takes to rotate relative to the stars. Since the Neptune year is 60,190 earth days, you need to figure out how many Neptune sidereal days that is. (Answer: 89,669 Nep. sr days). Then figure out what time period is 1/ 89,669 of a Nepture sr day. (Answer: 0.65 seconds).
