In the past few years, astronomers have made some strides in improving technology for their telescope and computerized data analysis and they have been able to spot over 350 extra solar planets in more than 275 separate system within a few hundred light years of the Sun. Of course the techniques used to find them are generally indirect, based on analysis of light from the parent star, not from the unseen planet. Bottom line is everything is empirical with some technological advance to help us get a closer look and it's going to take a while. For instance, does anything look a little like a Nebula theory out there, yet it's just starting out

What else can I help you with?
What is an example for astronomy?
An example of astrophysics could be the process of which stars are "born" and "die," and it differences from astronomy because it is (astronomy) mostly observational e.g. search for asteroids and planets.
What is the planet on which the sun does not rise and set?
All planets that rotate in our solar system will see apparent sun rise and sun set There are no planets that are stationary not to view the apparent sun rise and sun set.
The set of planets in our solar system with a name that starts with the letter M?
mars
What is the clockwork model of the solar system called?
The clockwork model of the solar system is called the heliocentric model. It proposes that the Sun is at the center of the solar system with the planets, including Earth, orbiting around it in a set, predictable pattern. This model was proposed by astronomers such as Nicolaus Copernicus and later refined by Johannes Kepler and Galileo Galilei.
What characteristics set the inner planets apart from the outer planet and name the outer planets?
The inner planets are all rocky planets, whereas the outer planets are gas giants. Pluto is the exception. The outer planets also make 99% of our planets and are outside the asteroid belt.
Are extrasolar-planets real?
Yes, about a thousand extrasolar planets have been discovered so far. However, not much details are known about them - for example, it's too early to tell whether there is life on any of them.
Why are the planets closest to the sun made of solids and the far planets made of gas?
The planets closest to the sun are made mostly of solids because the heat from the sun prevented lighter gases from accumulating there. The outer planets are farther away and cooler, allowing them to capture and retain lighter gases like hydrogen and helium, making them gas giants.
Why are planets named after roman gods?
That was the practice in Roman times, for the 5 planets visible to the naked eye: Mercury, Venus, Mars, Jupiter and Saturn. Later, European astronomers adopted these as a common reference. It also set a precedent for naming Uranus (for Greek god Ouranos), Neptune (Roman god of the sea), and Pluto (Roman god of the underworld) when these planets were discovered.
What set of planets have more moons terrestrial or gas?
gas planets

Who is the greek astronomers who set up a system for measuring the magnitude stars?
galileo
Does the sun set on other planets?
Yes
Which set of planets is earth in?
Inner or terrestrial
What are three major things that set earth apart from other planets?
The three major things that set earth apart from other planets is atmosphere, climate, and weather.
What is the planet on which the sun does not rise and set?
All planets that rotate in our solar system will see apparent sun rise and sun set There are no planets that are stationary not to view the apparent sun rise and sun set.
Which planets can we set foot on?
We can set foot on all the planets in the solar system including the terrestrial planets, except for gas giants, which are Jupiter and Saturn. We can't set foot on Jupiter and Saturn because there's no solid surface and it's so gaseous. Uranus and Neptune are also a gas giant but they're considered an ice giant, so there's a solid surface in these 2 ice giants. We can set foot in all planets except for Jupiter and Saturn.
