Mass forming planets = 60% of 5 × 10³⁰ = 0.6 × 5 × 10³⁰ = <<0.6*5e30=3e30>>3 × 10³⁰ kg.

Title: The Role of Mass in Planet Formation – How 60% of 5 × 10³⁰ kg Shapes Our Solar System When exploring how planets form, mass is one of the most critical factors in determining whether a celestial body becomes a full-fledged planet or remains a minor object like a moon or asteroid. Recent calculations reveal that roughly 60% of 5 × 10³⁰ kg — or 0.6 × 5 × 10³⁰ kg — defines the critical mass threshold for planet formation in protoplanetary disks. This value, often expressed as 3 × 10³⁰ kg (≈0.6 × 5 × 10³⁰ kg), marks the delicate boundary between planetary growth and fragmentation in the early solar system. --- ### What Is the 60% Mass Threshold?
