How long is the Sun in km?

How long is the Sun in km?

The mean radius of the sun is 432,450 miles (696,000 kilometers), which makes its diameter about 864,938 miles (1.392 million km). You could line up 109 Earths across the face of the sun, according to NASA (opens in new tab). The sun’s circumference is about 2,715,396 miles (4,370,006 km).

How far away is the Sun right now?

The Sun is at an average distance of about 93,000,000 miles (150 million kilometers) away from Earth. It is so far away that light from the Sun, traveling at a speed of 186,000 miles (300,000 kilometers) per second, takes about 8 minutes to reach us.

How far away is the Sun by car?

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.

What is the hottest planet?

Venus’ thick atmosphere traps heat creating a runaway greenhouse effect – making it the hottest planet in our solar system with surface temperatures hot enough to melt lead.

How hot is the sun?

What is bigger than the sun?

Jupiter’s mass is nearly times that of the Sun. Sirius, Pollux, Alpha Centauri A, UY Scuti etc. are some examples of stars bigger than the sun.

Do we see the sun 8 minutes ago?

Minutes and hours The Sun is about 150 million km away, so we see it as it was about 8 minutes ago. Even our nearest planetary neighbours, Venus and Mars, are tens of millions of kilometres away, so we see them as they were minutes ago.

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.

Is sun getting hotter?

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.

How heavy is the sun?

How long will it take to fly to the sun?

At this speed, how many days would it take to travel to the sun from Earth, located at a distance of 149 million kilometers? Answer: Time = Distance/speed so Time = 149,000,000 km/ 28,000 = 5321 hours or 222 days.

How close can NASA get to the sun?

The spacecraft will fly through the Sun’s atmosphere as close as 3.8 million miles to our star’s surface, well within the orbit of Mercury and more than seven times closer than any spacecraft has come before. (Earth’s average distance to the Sun is 93 million miles.)

Which is coldest planet?

Uranus holds the record for the coldest temperature ever measured in the Solar System: a very chilly -224℃. The temperature on Neptune is still very cold, of course – usually around -214℃ – but Uranus beats that.

Which is the brightest planet?

Venus, which can be seen with the unaided eye fromEarth, is the brightest planet in our Solar System. Venus was given the nickname evening star and morning star because of its bright, consistent presence.

What is the 2nd heaviest planet?

Hence second biggest planet in the solar system is Saturn. Was this answer helpful?

Is the Sun 7 minutes away?

The Sun is 93 million miles away, so sunlight takes 8 and 1/3 minutes to get to us. Not much changes about the Sun in so short a time, but it still means that when you look at the Sun, you see it as it was 8 minutes ago. Photo of the Sun in hydrogen-alpha light.

Is the Sun 150 km away?

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.

Is km bigger than light years?

A light-year, alternatively spelled light year, is a large unit of length used to express astronomical distances and is equivalent to about 9.46 trillion kilometers (9.46×1012 km), or 5.88 trillion miles (5.88×1012 mi).

How long does it take light to go 1 km?

0.0000033 seconds to travel 1 kilometer; 1.3 seconds to reach us from the Moon; 8.32 minutes to reach us from the Sun; 4.37 years to reach us from Alpha Centauri, the nearest star system to the Solar System (Alpha Centauri is therefore said to be 4.37 light years away);
