For an object to absorb light, it must be possible for photons (particles of light) to raise electrons to a higher energy level, and thus absorb the energy of the photon. If the possible energy levels of electrons don't allow this (for the particular range of energies that correspond to visible light), the photons won't be absorbed.
The planets positions change all the time. Some of the planets are easier to see. When they are visible, Venus, Mars, Jupiter and Saturn can easily be seen with the naked eye, if you know where to look. The other planets need a set of binoculars or a telescope to see them. Check the site below to help you locate the planets. Currently Jupiter can be seen for a while after sunset, as a bright object low and towards the south.
with your eyes
Mercury
the roam (go around) planets. they have a camera attatced to them so that we can see what the 'robot sees. usually we send these 'robots' to space to see if there is any life on planets.
Yes. To date scientists have discovered well over a thousand planets orbiting other stars. It is believe that a large portion of the stars in the night sky have planets.
by a telescope
See below-
The light we see from the planets is sunlight that has been reflected.
You can see some of the planets with the naked eye. The following can be seen easily; they appear as bright stars: Mercury, Venus, Mars, Jupiter, Saturn. To see other planets, telescopes are required.
You can see five of the planets in our Solar System with the naked eye - they appear as bright stars. To see Uranus and Neptune, you need telescopes.
because soem planets are to far away and our eyes cant see that far
because we have eyes
through a telescope
The Philippines are a very good place to see all the planets.
Astronauts can see planets, stars, and species.
because some of the planets reflect lights from the sun like Venus.
Yes
