Which telescope would be the most effective for viewing Erath Like planets?

Question

Refracting, Reflecting or Radio

Answer 1

Well first of all we don't know of any Earth-like planets. Planets around other stars are too distant and dim to be viewed directly with present-day telescopes (of any kind).

Planets have been detected indirectly by other means, but no pictures of them exist. There are plans to build space telescopes that combine their light to create a resolution fine enough to actually see planets around other stars, but that is a decade away.

Of course it's easy to view the other planets in our solar system with any type of scope, but I would recommend a reflector.

Answer 2

Reflecting. And even then, you need a lot of them all tied together into an interferometer, to directly image Earth-sized planets. Why a reflector, one might ask? Simple, you can assemble a much larger primary mirror than you can a refractor's lens (the largest refractor lens is just over a meter in diameter, and they can't get too much larger than that,) and you can send a large mirror into space, which is why the major space telescopes are all reflectors. And even then, you can't build a single telescope large enough to directly image an Earth-sized planet orbiting another star (you need a very tiny angular resolution to pick out something Earth-sized from that far away.) As a result, you need a fleet of telescopes flying in formation to form an interferometer, which is, simply put, a bunch of telescopes in formation which are combined to form a single telescope with an objective of the same effective diameter as the size of the interferometer.

Answer 3

Depends on what you mean by Earth-like planets.
In our solar system, the planets Mercury, Venus, Earth, and Mars are called the "rocky" planets. Jupiter, Saturn, Uranus and Neptune are called "gas giants".

For all of these, refracting or reflecting would be okay. Radio telescopes are generally used with radio sources, like Jupiter or quasars.

Refracting telescopes are generally smaller than 4 inches diameter. For larger sizes, reflecting telescopes are generally used.

Answer 4

it relatively is a mix of a unfavourable telescope, unfavourable eyepieces, and a shaky mount. severe magnifications are by no potential as sharp as low magnifications; this is in basic terms the guidelines of physics. With a stable telescope on a sturdy mount and with stable high quality eyepieces, the photos might stay particularly sharp and you may desire to change eyepieces without dropping the planet. you do no longer say which planets you're watching. Mars, Venus, and Mercury are all too some distance away at cutting-edge to teach something different than a tiny disk. Jupiter and Saturn are the only ones worth watching with a 60mm scope. Jupiter will teach its 4 moons and perchance a band or 2 on its disk; Saturn will teach the rings (which look like a toothpick at cutting-edge), one moon, and perchance the shadow of the rings on the disk (a skinny line).

Answer 5

No existing telescope can see an Earth like planet around another star. There are various proposals to build one that could, and I think they are all optical reflecting telescopes. But they are giant space based telescopes. It would be completely hopeless from the ground.

Answer 6

I went through that a few years ago and bought a telescope for my grand daughter and was very disappointed ,they live in the edge of a large3 town and the lights blind u so .It didn't work very well.
