What was the orbit of Sputnik 1?
What was the orbit of Sputnik 1?
Sputnik 1 eventually settled into an elliptical orbit, which took the satellite as close to Earth’s surface as 142 miles (228 kilometers) and as far away as 588 miles (947 km). The satellite zipped around Earth every 96 minutes.
How long did Sputnik 1 orbit the Earth?
about 98 minutes
History changed on October 4, 1957, when the Soviet Union successfully launched Sputnik I. The world’s first artificial satellite was about the size of a beach ball (58 cm.or 22.8 inches in diameter), weighed only 83.6 kg. or 183.9 pounds, and took about 98 minutes to orbit Earth on its elliptical path.
When did Sputnik first orbit the Earth?
October 4, 1957
The Soviet Union inaugurates the “Space Age” with its launch of Sputnik, the world’s first artificial satellite, on October 4, 1957.
What was special about Sputnik 1?
4, 1957, Sputnik 1 successfully launched and entered Earth’s orbit. Thus, began the space age. The successful launch shocked the world, giving the former Soviet Union the distinction of putting the first human-made object into space.
Is Sputnik still orbiting Earth?
Sputnik 1 burned up on 4 January 1958 while reentering Earth’s atmosphere, after three months, 1,440 completed orbits of the Earth, and a distance travelled of about 7.0×107 km (4.3×107 mi)….Sputnik 1.

What was the first animal to orbit?
dog Laika
The first animal to make an orbital spaceflight around the Earth was the dog Laika, aboard the Soviet spacecraft Sputnik 2 on 3 November 1957.
Was there a Sputnik 3?
This time, all went well and Sputnik 3 entered its planned elliptical orbit around the Earth, becoming the sixth artificial satellite after its two Soviet predecessors and three satellites that the Americans launched in early 1958. Sputnik 3 reentered the Earth’s atmosphere on April 6, 1960.
Is Sputnik still orbiting the Earth?
It achieved an Earth orbit with an apogee (farthest point from Earth) of 940 km (584 miles) and a perigee (nearest point) of 230 km (143 miles), circling Earth every 96 minutes and remaining in orbit until January 4, 1958, when it fell back and burned in Earth’s atmosphere.

What was a direct result of the 1957 launch of Sputnik 1?
On October 4, 1957, the Soviet Union launched the earth’s first artificial satellite, Sputnik I. As a result, the launch of Sputnik served to intensify the arms race and raise Cold War tensions. During the 1950s, both the United States and the Soviet Union were working to develop new technology.
The performance of the launch vehicle was slightly lower than expected, resulting in an orbit of 228 km, an apogee of 947 km, and an orbital inclination of 65.1 degrees with an orbital period of 96.17 minutes. The satellite worked for 21 days. Sputnik 1 reentered the atmosphere and burned up on 4 January 1958.
How did Sputnik determine the density of the upper atmosphere?
The density of the upper atmosphere could be deduced from its drag on the orbit, and the propagation of its radio signals gave data about the ionosphere . Sputnik 1 was launched during the International Geophysical Year from Site No.1/5, at the 5th Tyuratam range, in Kazakh SSR (now known as the Baikonur Cosmodrome ).
What was the orbit of the first Space Shuttle?
Sputnik 1 was successfully launched on 4 October 1957 at 19:28:34 GMT. The performance of the launch vehicle was slightly lower than expected, resulting in an orbit of 228 km, an apogee of 947 km, and an orbital inclination of 65.1 degrees with an orbital period of 96.17 minutes.
How did the launch of Sputnik 1 affect the American public?
The launch of Sputnik 1 surprised the American public, and shattered the perception created by American propaganda of the United States as the technological superpower, and the Soviet Union as a backward country.
