You can see things with the naked eye- you can see them well. They are cheap. They are easy to use (you don't need training) Easy availability (you can get them from Tesco's) They gave us good early info (Gallieo used them to try and prove that the Earth revolved round the sun- not the other way round!) •
The orbital names s, p, d, and fstand for names given to groups of lines in the spectra of the alkali metals. These line groups are called sharp, principal, diffuse, and fundamental.
Telescope eyepieces are important of any visual telescope. It is the main part of the telescope and is what determines how the object will look like through the telescope.
The s orbital fills before the p orbital because it has lower energy, and is more stable.
simplest possible telescope
Newton was English. He made many contributions including inverting the reflecting telescope and formulating a quite good theory of gravity and orbital mechanics. He shares the invention of the calculus with Leibniz.
The Hubble space telescope is in near Earth orbit at a orbital height of 559 km (347 miles)
HST orbits the Earth every 97 minutes at an orbital altitude of 347 miles.
we benefit from him because of his military compass, telescope we still use today
The Hubble Space Telescope has an orbital velocity of 7,500 m/s (meters a second) or nearly 17,000 mph.
The Hubble's orbital altitude is about 559 km (347 miles) above the Earth's surface ... less than half of the distance from New York to Chicago.
HST orbits the Earth approximately 15 times daily, or about 96 minutes per orbit. You can see its orbital track and learn more about it at the link below.

It doesn't orbit earth faster. The ISS is in a lower orbit with a period of 91 minutes compared to the Hubble's orbital period of 96-97 minutes. Orbital periods generally increase with orbit radius and speed in the orbit decreases with increasing orbit radius.
The s orbital is the orbital nearest to the nucleus in an atom.
There are a couple of techniques. The one used by the Kepler Space Telescope uses the tiny differences in the apparent brightness of a distant star when a planet passes between that star and the Kepler Space Telescope. By analyzing the light patterns over a period of time, we can calculate the orbital period of the planet around the star. Please note that in order for this to work, the distant solar system's orbital plane must be precisely aligned with the Earth; if the orbital plane were tipped even slightly, the planet would never pass between the Kepler and the star. So it's pretty limited in which planets it might detect. However, the fact that the Kepler Space Telescope has discovered thousands of extra-solar planets means that planets must be as common as dirt. We used to believe that planets might be rare; now we're pretty sure that they are quite common.
It is a reflecting telescope
due to difference in orbital time planets will sometime be same side of sun sometimes opposite side, hence there can be a huge difference in how big the planet looks.
