You can see the six ancient planets without a telescope when they are visible, and in theory you can also see Uranus in perfect conditions. Neptune needs a moderate-sized telescope like a 3" refractor.
You can see all of the following with the naked eye: Mercury, Venus, Mars, Jupiter, Saturn. Since Venus and Jupiter are very bright, you are most likely to notice those.
a telescope because if you never heard of the Hubble telescope that is like the international telescope.
not much. For a telescope to be useful at 525x power it would have to be 250mm and you would need very good atmospheric conditions (a rarity). A 70mm telescope can be used at about 100x provide it is a high quality one.
Out doors, at night. The darker the sky (the further away from city lights) the better.
A refracting telescope uses the most direct light path, relying on lenses (rather than prisms and mirrors) to provide a focused image of the night sky.Its opposite would be the reflecting telescope.
We wouldn't lnow about the world being a sphere and about all the discoveries he made about the planets. We wouldn't have such an advanced telescope, and the theroimeter would of never existed.
Mercury, Venus, Mars, Jupiter, and Saturn are visible from Earth without a telescope. At certain times, for those with excellent vision, Uranus is visible. Some planets are best viewed just before dawn.

To measure pressure in the air. Meteorologists use them (weather people) a barometer is used for measuring pressure,the units for measuring pressure include atm,pascal,torr,mm of hg,bars.
Things can actually be larger or smaller than they look depending on their distance from you. On this website, if the planets were listed as the same size, they appear different sizes from a telescope because they are different distances from Earth.
look through a telescope at night
Saturn is one of five planets that you can see in the night sky without a telescope. The others are Mercury, Venus, Mars, and Jupiter. Anyone who spent a good deal of time watching the night sky would realize that these objects moved relative to the background of stars.
An Astronomer
Yes. You are able to see Jupiter with a telescope from Earth at certain points in the year.
a hubble space telescope
When you observe through a telescope at night, so wherever you would do that.
There are only five planets which can be observed by common telescopes. The astronomical telescopes are normally installed and owned by governments and large research institutes. Mount Wilson observatory has reflective telescope with 100inch mirror. For non-professional, who wishes to study moon telescope with 3 inches aperture is good enough but to to study Saturn and Jupiter one would need nearly 10inch aperture telescope..
