Earth's slightly elliptical orbit means that our distance from the sun changes by a little over 3% in the course of a year. At aphelion today, Earth will be 94,502,714 miles (152,087,376 km) from our star, about 3 million miles (5 million km) farther away than we will be 6 months from now.

Guess who's coming for dinner...

Yesterday, Filipp Romanov used a remote telescope in Chile to capture this photo of an object suspected to have come from outside our solar system. And now it's official! Having further studied the space rock's orbit, the Minor Planet Center designated the object 3I/ATLAS yesterday evening, with '3I' meaning it's the 3rd interstellar object scientists have ever identified. And early signs suggest it's a comet. Find out more.

I enjoy getting this in my email,, Enjoy!
