When were telescopes used to see Uranus Neptune and Pluto?
All of those objects were discovered by telescope, so it's safe to say that telescopes were used from day one for each.
When were telescopes used to photograph the planets?
On march 1610
What tools were used to study uranus?
Telescopes are the main tools used to study Uranus. Ground-based telescopes and space telescopes like the Hubble Space Telescope are used to observe Uranus and analyze its composition, atmosphere, rings, and moons. Other tools include spacecraft missions like Voyager 2, which provided close-up observations of Uranus when it flew by the planet in 1986.
What planets orbit was used to predict the exictence of another planet?
Neptune was discovered in 1846 through observations of Uranus. Uranus' orbit was seen to appear to alter slightly through the gravitational effect of another planet, which turned out to be Neptune.
What planets did newton used to discover his theory of gravity to show its effects on Uranus?
Neptune.
When were telescopes used to see and to photograph the planets Neptune Uranus and Pluto?
Saturn was the outermost planet known until William Herschel discovered Uranus in the late 18th Century, so unless you count this as ancient, it would be inaccurate to say that the ancients could 'see' the planets beyond Saturn. Telescopes are first definitely attested in the early 17th Century. Photography in the modern sense (using a camera to record sharp images on a light-sensitive film, as opposed to more basic forms like the pinhole camera) didn't exist until the early 19th Century. I'm guessing that your question arises from the (quite sensible) assumption that all of the planets were named by the ancients, but this is not the case. The 'trans-Saturnian' (if you'll pardon the term) planets were named after Greek and Roman deities by later astronomers. Interestingly, Uranus and Pluto are named after Greek gods, rather than the Roman gods that give the other planets their names. I suppose that 'Caelus' and 'Dis Pater' didn't quite have the same ring to them. Hope this helps.
What was the frist used to discover Neptune?
Mathematical calculations to explain unexpected changes in the orbit of Uranus.
What prompted the astronomers to look for neptune?
They discovered Neptune in 1846, by examining the orbits of the other gas giant planets, particulary Uranus. Its slight deviation in orbit was as a result of neptunes gravitational effect.
How is Neptune been studied and what tools have been used?
Neptune has been studied using telescopes such as Hubble, ground-based observatories, and space probes like Voyager 2. Scientists also use computer simulations to study Neptune's atmosphere, magnetic field, and internal structure. Additionally, radio telescopes are used to study radio emissions from Neptune.
How many people have seen on Uranus?
As of now, no humans have physically visited Uranus. The planet has only been observed remotely through telescopes and by the Voyager 2 spacecraft, which flew by in 1986, providing valuable data and images. Thus, the number of people who have "seen" Uranus is limited to those who have used telescopes or received data from spacecraft, rather than direct observation.
