A journey through our solar system
Explore the solar system — pick a spacecraft, choose a destination, and fly!

YOUR NEXT HORIZON
One spacecraft. An extraordinary distance.
Choose your destination and spacecraft before launch.
A straight-line, constant-speed comparison using approximate nearest or farthest Earth-to-destination distances. The departure date does not determine planetary alignment. Speeds represent different flight conditions; a record near the Sun is not a sustainable cruising speed to another planet. Gravity, acceleration and orbital trajectories are not modeled.
