Neutron Stars: 

• 20 km in diameter
• 1.4 times mass of our Sun
• Surface gravitational field of about 2 x 10¹¹
• One possible end to a star
• Appear in supernova remnants, isolated objects, or binary systems
• Four known Neutron Stars have planets

Pulsars: 

• Rotating Neutron Stars that appear to pulse due to the rotation
• Discovered in 1967 by Jocelyn Bell Burnell
• Jets of particles shoot out almost at the speed of light above the magnetic poles
• Spin axis and Magnetic axis are disaligned (similar to Earth)
