Could be the solenoid. Find it, push the start button, and rap the solenoid with a screwdriver. If it starts, swap the solenoid. If it doesn't, jump across the solenoid or use jumper cables and jump directly to the starter. If it starts, swap the solenoid. If it still doesn't, swap the starter.
It could still be the battery though, so might want to try to jump start it from your car, but don't do it with the car running, just from the car battery.
