How much energy is required to fuse two protons? [closed]

What is the kinetic temperature required to fuse two protons in a plasma? How much energy does it release? What are the products of the fusion reaction?

• Note that fusing two protons almost always yields a diproton, which is unstable and immediately falls apart. Apr 29, 2020 at 8:13
• How often does it fuse into Deuterium? Apr 29, 2020 at 8:47
• I do not know the exact number, but it is a vanishingly small probability that enables the Sun to continue fusing hydrogen for about 12 billion years. Apr 29, 2020 at 10:04

$$p + p → D + e^+ + ν_e$$
