How far away is the Sun in miles exactly?

As noted earlier, Earth’s average distance to the Sun is about 93 million miles (150 million kilometers) from the Sun. That’s 1 AU. On average, the sun is 93 million miles from the earth. It would take 1,430,769 hours to drive there at 65 miles per hour. Earth travels around the sun in an orbit that is slightly oval-shaped, known as an ellipse. Therefore, the planet’s distance from the sun changes throughout the year. However, the average distance from Earth to the sun is about 93 million miles (150 million kilometers). Our Sun is a medium-sized star with a radius of about 435,000 miles (700,000 kilometers). Many stars are much larger – but the Sun is far more massive than our home planet: it would take more than 330,000 Earths to match the mass of the Sun, and it would take 1.3 million Earths to fill the Sun’s volume. While space starts 62 miles above Earth’s surface, the Moon is much farther away. On average, it orbits 238,855 miles (384,400 kilometers) from Earth.

How heavy is the sun?

Can we travel to sun?

The sun’s surface is about 6,000 Kelvin, which is 10,340 degrees Fahrenheit (5,726 degrees Celsius). The sun would melt anything that got near it. But we can send robotic probes toward the sun and even around it. The temperature at the surface is nearly 6,000 degrees Centigrade. The gases move at thousands of miles an hour. You can’t stand on the surface of the Sun even if you could protect yourself. The Sun is a huge ball of heated gas with no solid surface. No. Outside mythology, no human has ever attempted to travel to the Sun. The main reason is fairly obvious—it’s too hot. Even in a well-protected spacecraft, you could only get within about 2 million kilometres (1,300,000 mi) before burning up. Warmth: not too much and not too little And we get the amount of warmth needed for humans, animals and plants to live. If the sun would go out, no life could survive on most of earth’s surface within a few weeks. Water and air would freeze over into sheets of ice. You might think it would suddenly become very cold. But it wouldn’t. You wouldn’t even notice the difference. Our planet has stored enough heat in its atmosphere and oceans to keep us warm for those five seconds without the Sun.

How far is 1 light-years away in miles?

A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). That is a 6 with 12 zeros behind it! Surprisingly, the answer has nothing to do with the actual speed of light, which is 300,000 kilometers per second (186,000 miles per second) through the vacuum of empty space. While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day. But this is still only half of the story The sunlight we see is 170 000 years and 8.5 minutes old. It is ancient! Explanation: The clocks in space tick more slowly than clocks on Earth., HENCE COVERING LESS TIME AS COMPARED TO EARTH IN THE SAME DURATION. One hour on Earth is 0.0026 seconds in space. Thus, upon calculation we find that one hour on Earth is equivalent to seven years in space.

Is The Sun getting bigger?

Because the Sun continues to ‘burn’ hydrogen into helium in its core, the core slowly collapses and heats up, causing the outer layers of the Sun to grow larger. This has been going on since soon after the Sun was formed 4.5 billion years ago. At its core, the sun burns millions of tons of hydrogen every second in a process called nuclear fusion. Fusion turns hydrogen into helium and releases incredible amounts of energy in the process. It’s fusion that creates the heat and the rays of light that eventually reach Earth. Eventually, the fuel of the sun – hydrogen – will run out. When this happens, the sun will begin to die. But don’t worry, this should not happen for about 5 billion years. After the hydrogen runs out, there will be a period of 2-3 billion years whereby the sun will go through the phases of star death. If the Sun was more like a red dwarf, it could last much longer. In order to save the Sun, to help it last longer than the 5 billion years it has remaining, we would need some way to stir up the Sun with a gigantic mixing spoon. To get that unburned hydrogen from the radiative and convective zones down into the core. Over the past 4.5 billion years, the Sun has gotten hotter, but also less massive. The solar wind, as we measure it today, is roughly constant over time. There are the occasional flares and mass ejections, but they barely factor into the Sun’s overall rate at which it loses mass.
