Observers have known about Mercury's existence since antiquity, but it's difficult to study because of its position in the solar system. In the first installment of the "Tour the solar system" series, Associate Editor Liz Kruesi explores what scientists know about the innermost planet and what they're still hoping to learn in the future.

In this particular video, I talk about some of the basic properties of Mercury and a few of the MESSENGER spacecraft's discoveries. Our video department did a wonderful job incorporating the images and piecing together the final product.
You can let me know what you think about this first installment in the comments section below, and get excited for the others in the series coming soon!
