When will we be able to visit the sun?

When will we be able to visit the sun?

  1. Hi Eleanor, the Sun is likely going to be around for the next 4 billion years so we’ve got plenty of time if we want to visit it.

    However, if you do try to get near it, you’re likely to get very hot. The surface of the sun is several thousand degrees centigrade. Even the most tough material on earth will melt at this temperature.

    Even if you were to find a suit to wear which would protect you from the heat, you would not be able to look at the sun as it’s so bright. In fact, it’s bright enough for us from Earth that looking into directly into the sun can damage our eyes. We are 150 million kilometres from the Sun, so imagine how bright it would be if you were to visit it!

    The Sun is a lot heavier than the Earth too, it’s over 300 thousand times heavier, and this means that gravity on the Sun also has a bigger effect. It’s likely that you just wouldn’t be able to stand up on the Sun as you would be pulled towards it much more. And it would be impossible to escape when you had landed on it, as you would need a great deal of energy to “launch” yourself off it. We already need very big rockets to launch ourselves off the Earth!

    In summary, I don’t think that visiting the Sun would be a great idea. There wouldn’t be anyone there to visit, and we probably wouldn’t be able to leave!
