How many year a spacecraft Travelling at the speed of a jet will take to reach Sun?

How many years would it take a rocket traveling at the speed of the International Space Station to make this journey? Answer: Time = 4,500,000,000 km / 28,000 km/h = 160714 hours or 6696 days or 18.3 years. Problem 3 – The fastest unmanned spacecraft, Helios-2, traveled at a speed of 253,000 km/hr.

Where is the farthest a spacecraft has gone?

The most distant artificial object is the spacecraft Voyager 1, which – in November 2021 – is nearly 14 1/2 billion miles (23 billion km) from Earth. Voyager 1 and its twin, Voyager 2, were launched 16 days apart in 1977.

Is it possible to reach the sun?

In theory, we could. But the trip is long — the sun is 93 million miles (about 150 million kilometers) away — and we don’t have the technology to safely get astronauts to the sun and back yet. The sun would melt anything that got near it. But we can send robotic probes toward the sun and even around it.

Is it possible to orbit the Moon in a 10-meter orbit?

Not as low as 10 meters, no, because the surface of the Moon varies by much more than that. But you can get pretty low orbits. Here for example is an orbit with initial average altitude of 124 km (semimajor axis 1861 km) and stable for 4000 days, or about ten years.

How long can a spacecraft stay in a low lunar orbit?

“There are actually a number of ‘frozen orbits’ where a spacecraft can stay in a low lunar orbit indefinitely. They occur at four inclinations: 27º, 50º, 76º, and 86º”—the last one being nearly over the lunar poles.

How long does it take for a Moon orbit to freeze?

They have a period of about 2 hours. They are of particular interest in exploration of the Moon, but suffer from gravitational perturbation effects that make most unstable, and leave only a few orbital inclinations possible for indefinite frozen orbits, useful for long-term stays in LLO.

What is the height of the Moon when the LM landed?

The LM began its landing sequence with a Descent Orbit Insertion (DOI) burn to lower their periapsis to about 50,000 feet (15 km; 8.2 nmi), chosen to avoid hitting lunar mountains reaching heights of 20,000 feet (6.1 km; 3.3 nmi).
