I am not sure what exactly you mean with "planetary objects". To see planets, just look up in the evening, and watch out for objects that look like exceptionally bright stars. These days (October 2010), after sunset you can see Venus as a very bright star in the west, and Jupiter as a bright star (less bright than Venus, but otherwise exceptionally bright) in the east.
What else can I help you with?
Why can you see other planets and planetary satellites?
the brightest and the sixth biggest planet
Which is biggest a planetary nebula a planetary system or a galaxy?
A galaxy is the biggest among the three. Galaxies contain billions to trillions of stars, as well as other celestial objects like planets and planetary nebulae. A planetary system refers to a star with its orbiting planets, while a planetary nebula is a glowing shell of gas ejected by a dying star.
Why is the sun responsible for people's ability to see other objects within the solar system?
The Sun's light, falling on other objects, allows people to see planets and other objects, which would be dark otherwise.
Does gravity act only on objects with mass?
Yes, gravity is a fundamental force of nature that affects objects with mass. Objects with mass are attracted to each other due to gravity, creating phenomena such as planetary motion and the acceleration of falling objects.
Are there other planetary systems around other stars?
Yes. Many stars have planetary systems.
What is the planetary symbol of mercury?
See link.
Why do objects not attract each other?
If you refer to gravity: actually, they do. However, the force for everyday objects is very weak. Plug some numbers into the formula for gravitational force, to get an idea. This force mainly becomes relevant on planetary (or larger) scales.
What is planetary accretion?
Planetary accretion is the process by which smaller particles in a planetary system collide and stick together, gradually building up larger bodies like planets. This process is driven by gravity, as particles attract each other and form into increasingly larger objects over time. Accretion is a key step in the formation of planets from the protoplanetary disk around a star.
How is the planet Eris affected by gravity?
Planet Eris is affected by gravity like any other celestial body in our solar system. It has its own gravitational force that holds objects on its surface and influences other objects around it. Gravity also affects the orbit of Eris as it interacts with other planetary bodies in the solar system.
Does Mars' gravity affect other objects?
Yes, Mars' gravity affects other objects just like any other planetary body. The strength of Mars' gravity is about 38% of Earth's gravity, so objects will weigh less on Mars than on Earth. This weaker gravity also influences things like the orbit of spacecraft around Mars.
Are there any solar sytems outside of the Milky Way?
Technically the Solar System is our system - Sol = Sun. However, as this term was derived when we knew little about our own Solar System - let alone other "objects" outside of it. Since then, we have discovered over 500 exoplanets [See related question]. So there are other planetary systems orbiting other stars.
Can lizards see humans and distinguish them from other objects?
Yes, lizards can see humans and distinguish them from other objects. They have good vision and are able to recognize different shapes and movements, including those of humans.
