yeah about 450 miles
In 2005 a satellite went into orbit around Venus.
From the question, I'm guessing that when the questioner reads the term "polar orbit", he's picturing the satellite doing a little tiny circle in the sky over the North Pole. This is not an accurate understanding of the term. Remember that the center of the orbit of an artificial satellite has to be at the center of the earth. A 'polar orbit' is an orbit that covers both poles. If you picture the globe of the earth, the satellite's orbit is a circle standing up, with the satellite traveling up and down, passing over both poles in each complete revolution of the earth. As the earth rotates, every point on earth passes under the orbit, and sooner or later, every point on earth will be visible from the satellite.
All satellites pass the equator. Twice every orbit.
You don't really have a question here. If the satellite is in orbit, the mass is essentially irrelevant; it wouldn't change the speed of the orbit or the altitude. A larger satellite mass WOULD HAVE required more fuel and more energy to LAUNCH it, but once in orbit, it will stay there. The only exception would be an exceptionally large, light satellite. There is still some minuscule traces of atmosphere at 200 miles, and a large, light satellite would be slowed by air friction much more than a small dense satellite would. This is what caused the "ECHO" satellite - essentially a silvered mylar balloon inflated in orbit as a primitive reflector comsat - to deorbit.
A polar orbit (as opposed to an equatorial orbit) passes over the poles, north and south. A low orbit is relatively close to the Earth (or other object being orbited), it might be a few hundred miles up.
YES As height increases, speed of satellite decreases.
The orbit helps the satellite go into orbit.
CARTOSAT 2A is an Earth observation satellite in a sun-synchronous orbit. The satellite is the thirteenth satellite in the Indian Remote Sensing (IRS) satellite series to be built, launched and maintained by the Indian Space Research Organisation.
A satellite orbiting around the Earth's poles is in a polar orbit. This type of orbit allows the satellite to pass over different parts of the Earth as it rotates below. Polar orbits are often used for Earth observation and surveillance satellites.
The Philippines has multiple satellites in orbit for various purposes such as communication, weather monitoring, and earth observation. Some examples include DIWATA-1 and DIWATA-2, the Philippine Scientific Earth Observation Microsatellite (PHL-Microsat), and Agila-2, a geostationary communications satellite.
The mass of a satellite does not affect its orbit. The orbit of a satellite is determined by its speed and the gravitational pull of the object it is orbiting around, such as a planet. The mass of the satellite itself does not play a significant role in determining its orbit.
A secured orbit refers to a stable and controlled path that a satellite follows around a celestial body, such as Earth. It involves maintaining a specific altitude, speed, and trajectory to ensure the satellite remains in its designated orbit without interference or deviation. This is crucial for the satellite to perform its intended functions, such as communication, observation, or navigation.

A Geostationary orbit - it means that the satellite will always stay above the same point on Earth. Hope that helps
The repetitivity and revisit of satellite orbit refers to the time elapsed between observations of the same point on earth by a satellite. It usually depends with the target location, the orbit of the satellite and the swath of the sensor.
The very first satellite put into orbit was the Russian satellite Sputnik put into orbit on October 4th, 1957.
Gravity keeps satellites in orbit. The closer you are to the Earth, the faster you have to go to maintain your orbit. At low Earth orbit, the altitude of the Space Station, you make an orbit every 90 minutes. At the Moon's distance you need over 27 days to go around the Earth. In-between there is an altitude which matches the rate of the Earth's rotation. Many satellites orbit at this altitude.
