How many satellites are visible in the sky?
The number of satellites visible in the sky at any given moment can vary widely, but typically, around 20 to 30 satellites can be seen with the naked eye under optimal conditions. This includes both operational satellites and defunct ones. However, the total number of satellites currently in orbit is over 3,000, with many more being smaller and not visible without the aid of telescopes or specialized equipment. Factors such as light pollution and the satellite's orbit also affect visibility.
There are currently broadcasting GPS satellites?
Yes, there are currently multiple GPS satellites in orbit that provide positioning, navigation, and timing services globally. The Global Positioning System (GPS) is maintained by the United States and typically consists of around 30 operational satellites, ensuring that at least four satellites are visible from any point on Earth at any time. These satellites transmit signals that allow GPS receivers to calculate precise locations. The system is continuously being updated and improved to enhance accuracy and reliability.
Except for light reflection does a satellite eminate any other visible light during night time?
I am not aware of any beacon lights on any satellites. I'm sure the International Space Station has some, for times when the Shuttle is coming in, but what purpose would they serve otherwise? Aircraft have anti-collision lights - to avoid airplanes crashing into each other at night. But satellites generally travel too fast for any visual cues to be useful - and satellites have very limited maneuverability anyway.
Where are gps satellites located?
GPS satellites are located in medium Earth orbit, approximately 20,200 kilometers (about 12,550 miles) above the Earth's surface. They are arranged in six orbital planes, ensuring that at least four satellites are visible from any point on Earth at any given time. This positioning allows for accurate triangulation of locations by receiving signals from multiple satellites.
Has a longer wavelength than visible light can be used in cooking and communication with satellites?
Microwaves have a longer wavelength than visible light and are commonly used in cooking, as they are able to penetrate food and cause water molecules to vibrate, generating heat. Microwaves are also used in satellite communication to transmit signals due to their ability to travel through the Earth's atmosphere and interact with satellites in orbit.
Four of Jupiters satellites can be seen from Earth using a telescope What makes these satellites visible?
light emitted by the satellites

Why does the satellite suddenly stop being visible?
A satellite can stop being visible due to factors such as entering the Earth's shadow, changing its orbit, or switching off its reflective surfaces making it harder to see from the ground. Additionally, atmospheric conditions, like clouds or light pollution, can also obstruct visibility of satellites.
When are satellites visible?
When they reflect the light from the sun or moon.
Are there any visible satellites from Concord New Hampshire?
no
Where can one find pictures of earth satellites?
One can find pictures of earth satellites on the NASA Visible Earth online website. NASA Visible Earth is a catalog of NASA images of our home planet, earth. The website "Geology" is where one can also find pictures of earth satellites.
Are planets satellites of the sun?
Yes, the planets can be described as being satellites of the sun.
Are the planets are satellites of the sun?
Yes, the planets can be described as being satellites of the sun.
How do geographers use satellites to study earth?
Satellites carry cameras (visible light, infrared and ultraviolet)and radar. They produce very good images of the earth that can be studied.
What do false colour images from visible light satellites show us?
it shows us nothing
